Try to learn git (i suggest using Codeberg instead of github). You will make mistakes and it helps you revert to a time when your game worked and testing out possible mistakes without duplicating the entire folder X times.           

Use as little AI as possible. If not for moral reasons then for it making activly stupid and low skilled. Its a move fast, break things and learn nothing approach to use AI instead of the slow but steady brain.             

Use begginner tutorials for a jumpstart, they are here for that reason.            

Maybe try something small at first like a CONVERTER THAT REVERSES CAPS LOG TEXT or a calculator that only can addition. (the second is easier i think)       

Download godot and start messing around with it

If you want to make 2D games the LÖVE engine is pretty neat. It's what was used to make Balatro.
