Godot is an incredibly mature and actively developed open source game engine. You cannot start with something better, not without weird licensing compromises or financial contracts if you make enough money your game using their engine.

There are plenty of resources. The structure of development is very unique, but also very intuitive, so please don't get discouraged if anything seems new.

On a personal note, I implore you to refrain from using ChatGPT and learning to program things yourself. The tutorials are very thorough, and the graphical interface is thorough and robust enough that you will probably be programming less than you think, and of course with time it gets easier. Documentation is built in and searchable. The Godot Scripting language is Python like, which is a very easy language to learn.

The only tips really is to read through all the tutorials and make as many games as you can think of. Start small and stay small. All big systems are just tiny systems strung together.

Do not worry about making your own assets, unless you are an artist already.
