"I'm poor because I have massive debts" means you've chosen to borrow beyond your means, and need debt management.
No, it means I'm poor and dont have the disposable income to throw at bills or unexpected expenses.
I am a single parent on not much more than NMW who shares custody of my DD with her dad 50/50 (so no maintenence etc). Up until last year when we moved into a HA flat after 5 years on the council list (5 years of refreshing the property list at 00.01am every Thursday when the new bidding week started to bid on anything that we were eligible for) we lived in a private rental because I don't earn enough to be able to afford a mortgage alone never mind save the deposit needed but I could barely afford it as it was in a high CT area, water rates were exorbitant, the landlord had an old electrical system with two separate supplies (which was a legacy system they didn't want to update as it would cost thousands) that meant only one or two suppliers had a tariff to suit so I couldn't shop around for better deals etc but it was the only place that was available, suitable and just within my budget so I had to take it. I mostly managed to afford everything on my wage but we literally didn't have a spare penny and very occasionally I would have to put food shops on a credit card because the money just wouldn't stretch to the end of the month.
When I got my HA property it cost me just over £2000 upfront to move. In the long run it saved money as my rent/bills reduced but in order to do so it cost me money I didn't have. I bid on a property on the Thursday; got a call to offer a viewing the following Friday; viewed the property, agreed to rent it and was told I had to pay a month's rent (£500) on Monday as a deposit when I would be given the contract/keys and the tenancy was officially mine. If I didn't pay the rent by Monday the tenancy would go to someone else as they couldn't hold the property. Then, my next 4 months rent would be increased by 25% to cover the deposit (basically rather than paying deposit and one month's rent upfront they asked for the deposit up front and then split the first month's rent over a few months) so even though my new rent was £150 cheaper, I was only £25 better off for the first 5 months.
In addition, I had to give my current landlord notice of 1 month (£650) and as this all happened in the space of a week I was still on the hook for another months rent (fortunately this happened at the end of the month so my following month was the final one - if it had been a week or two later then I'd have had to pay the extra weeks) so I had to pay double rent for a month.
Then I had to pay to get the flat habitable - the previous tenant had spraypainted all over the walls; there were massive holes in the walls from where they had ripped out fixtures/shelves etc, all the seals in the kitchen and bathroom were crumbling/needed replacing and everything was just grotty, worn and in need of a good clean. Since I was paying rent to the old place I was lucky that I could do the work before I had to move all my stuff over but just to get it clean and painted cost about £300. Some of it was cosmetic so not life and death essential but would you want to live somewhere where your living room has "FUCK YOU CUNTS" painted in 3ft high neon pink spray paint?
Once it was habitable I had to actually get my stuff packed and moved - I don't have a car and while family were happy to help move boxes etc I needed to get packing stuff (I managed to get lots of free boxes at work but still needed to buy things like tape/rope/bubblewrap) and hire a man with a van for a day for the bigger furniture (beds/sofa etc) which cost me about £150-200.
Then I had to purchase all the white goods and other furniture - the private let was partly furnished and all white goods were integrated... the HA flat had a kitchen with a sink and a few cupboards so I had to buy a fridge/cooker/washing machine/microwave as we could not manage without them (washing machine I might have managed without at a push but there are no launderettes nearby and I would have had to take stuff to my parents, 20 mins away by bus, to do it). That cost me £600 as I got them new from a online discount place as I'd rather pay slightly more for new products that come with manufacturer and retail warranty, delivery and installation included than take my chance with some years old item of questionable provenance that someone was flogging for £50 on FB marketplace, (that would then have cost me an extra £50 get someone to collect/deliver it)
Then there were all the other furniture bits I needed eg clothes storage - at the private let all the bedrooms had built in cupboards so when we moved I needed to buy a wardrobe/drawers and even just buying a cheap fabric wardrobe and set of plastic drawers each for DD and I from B&M set me back £100 (still cheaper than FB marketplace/our local charity shops). Again not essential but I didn't want my DD to have to live out of boxes and suitcases for months on end because I couldn't afford to buy her a damn wardrobe.
By which time it was March 2020 and the pandemic hit. Overtime evaporated, my wages nosedived and my, originally manageable on my normal salary, debt became massive as I had no savings and had just had to put my entire move onto credit cards and my finances spiralled as I had to prioritise what bills were essential and what could afford to wait ... all the while late fees/interest were building up. Now I'm back to some sort of stability but, 18 months later my £2k moving costs are still owing because I had to prioritise food and rent than paying more than my minimum payment on my credit card.
I wish I had the privilege to just stop being poor and "live within my means", but even by trying to do so I've ended up in more debt.
