Just download the Godot engine[0] it's free and there are lots of tutorials on Youtube.
The documentation[1] also has a tutorial that shows you how to create a small 2D and 3D game. To learn programming with gdscript there is this free course by gdquest.[2]
Oh bollocks - looking at the Learn to Code From Zero link and it looks like just a modern version of those old "Learn to program a game in BASIC" books that were everywhere in the 80s when I was a kid.
