I’d say that while a full basketball game is a lot more complex, it’s made up of a lot of component tasks that still have objective success criteria: dribbling, passing, setting picks, doing your part in a play, etc. Ultimately your team either scores or it doesn’t.

Not to say it isn’t difficult, but I don’t think humans are doing anything particularly magical when they learn to play basketball—something I did myself when I was a kid. You learn each skill from a coach’s demonstration, practice them all a lot (practice = trial and error) and develop an intuition (reasoning) about what do to in various situations.
