Hey op, absolutely not true.
I studied fine art at Central Saint Martins, photography was my medium of choice.
I can think of a dozen of my classmates who went from being shocking at taking photos (rubbish composition, etc etc) to being incredibly good by the time the course ended.
Your use of colour is lovely. I really recommend doing some reading etc, once you get the rule of thirds down it’ll come even easier. I would lay off the filters etc whilst you’re learning though. Differential focus can make fabulous images, but you need to start with the composition first.
Please don’t give up! I used to use a Pinterest board to put all the ideas etc I wanted to try on a board.
I would say though, don’t set your sights on being a photographer. Everyone I know does it as a side hustle. It’s incredibly difficult to do as a career!
I’m not saying that to be negative. Just keep working on your photography skills and you’ll see so many more opportunities than being a photographer!
You are coming across as incredibly defeated. Your images are just normal photos, they aren’t photographer level but that doesn’t mean they can’t be. You need to put the work in! It’s takes years!
