You need to re frame your whole thinking on this.
Neither you or your baby are failing at this. Many many babies don't start eating significant amount of solids til well after 1. What's more, you definitely won't fail at this, there's no 9 year olds still only drinking milk. It will come, that's guaranteed.
Your only job is to encourage healthy habits and discourage unhealthy ones. Your baby will do the rest themselves.
I'd take the pressure completely off you both for a few weeks... just do milk only.
Then, start encouraging baby to eat with you, when you eat. Let baby have a little bit of what you're having if they wish, no worries if they don't. Just sit them in a high chair next to you and put a bit of what you have in front of them, let them decide what to eat, and how much. They can have a dollop of yogurt to smash and lick, steamed veggies, toast, shredded meat, grated cheese, scrambled eggs etc... just no added salt or sugar. Yes your diet too will be a bit blander for a while- but eat the same so baby sees how it's done. Chat about stuff about the day, about the food etc, but no well dones for eating or stress for not eating. If they don't eat no worries, just finish yours, ask if they're done, then take food away.
And repeat for days, weeks or months til they're eating! That's it.
But don't make it an emotional minefield for either of you... food is just fuel, not a battlefield.
I know this won't be easy for you to start with but what are you going to do otherwise? Never eat with your child? Look up videos of babies choking and babies gagging to learn the difference. Stay calm during gagging, baby is learning how to manipulate food within their mouth.
Also, I'd drop the veggies sticks and all nutritionally void stuff until they're well established on healthy normal food. That stuff is basically baby crack. I'd eat veggie straws all day if I could so I imagine same for babies...
