Uhh, you can't, or at least shouldn't, rely on chat gpt to replace your inability to code. It is a skill you absolutely will need sooner or later if you want to make a video game, unless you want finished solutions like game maker, fortnite editor or roblox (but even then I think you will need to script custom stuff sooner or later).
So I'd say take it easy and learn the basics first, do it proper and gain a skill while doing it. Forget about chatgpt and learn basics of programming languages, doesn't even matter which one as long as you like it, you need to get a feel and understanding of how code and computer logic actually works. I personally recommend python for beginners, which will translate nicely for gscript in godot down the line.
After that, I'd say sure go with godot. I personally like it more compared to unity but I haven't made any complete products with it, just messing around a bit and having fun. It's simple and easy to understand, relatively speaking.
Oh and definitely abandon these complex ideas for now. Make Pong as your first project and it will be challenging enough :D
