If you're lacking some general programming knowledge, i'd start with that (if you dont know how to program then you cant make a game despite what people may have told you).
Then you probably just need to learn the very fundamentals of the engine by reading the docs, instead of trying to learn this information through high level tutorials, so read all of this: https://docs.godotengine.org/en/stable/ (or at least the getting started part)
>I can't figure out how to move a sprite left on my own.
every node has a position variable which you can access through the global "position" variable in your godotscript. To move something left you just decrease the x value of its position variable. i.e.
func _process():
position.x -= 100
this is all explained in the docs & API reference
