Hi. I have a similar story to you. I also have learned programing my myself and have a little track when making games and some small programs. Not as a professional, and I am not a veteran, so you can skip my reply. Anyway.
Let's see if i got it right. Are you afraid that nobody want yo play your games because AI (and games created with it) exists?
If that's the case, then I will say that you are worried about nothing. Yes AI can ease software development, art making and stuff, yes there are a lot of shovel-ware made with AI. But a good games still is a good game, no matter the tool.
This is like saying nobody would play CoD of Battlefield because FPSCreator or GameGuru exists.
I think your concept is interesting and what you want to do is worth pursuing. The game after all will be 'judged' (in downloads, score, comments popularity) by it's overall quality. Little with matter if it was made with Fable,ChatGPT Codex, GODOT, Unreal and so on. If you have a good game and still doesn't have almost downloads or anything. Then the problem will likely be promotion/marketing side. Game Industry Is oversaturated since pretty much the 70's.
I made what i do pretty much as a hobby and more 'for me' I mean, I create stuff that I consider interesting or I want to see. And think little in a player base or a public. If i have it cool. Is not like i don't care about players/public, but i try 'likeing' others not be the main reason with I do stuff.
I just wrote that because perhaps you wanna ask yourself why you wanna games to begin with. Hobbie? wanna make money/fame? other? (there's no wrong answer, just different way to go depending the goal).
But again. Your game will be a good game and have it's public/niche/player base, etc because of you. No matter the AI you use or not use.
Wish you luck. :-)
