I’m a fairly serious golfer and appreciate John’s attempt at the analogy, but golfers don’t need to estimate collision angles off the nearest tree or rock. Until they get on the green and have to deal with slope estimation, every shot they have is “straight” - like hitting a pool ball directly into a pocket, which pool newbies learn to do easily. (Of course they factor in draws and fades - but still nothing like nailing a tough cut angle.)
That said, executing a straight golf shot is far, far tougher than executing a straight pool shot. Imagine playing pool from the side with a putter and having to control your clubface angle.
