I've heard that the earth, if scaled down to the size of a pool/billiards ball, would be smoother than the ball.
I often use that to explain how spinning cue balls can manage to change the angle of the shot, given the same impact point as a non-spinning cue ball, in an effect pool players call "throw." [1]
The peaks and valleys of the pool ball will reliably grip like gears. Sometimes the balls even stick together momentarily before they release, changing the outcome of the shot, in another effect called "skid". [2]
Also the referenced site is an amazing deep-dive into a niche topic, worth a glance--especially the high speed videos demonstrating the physics of the game.
