ELI5: What does putting chalk on the rnd of a cue stick actually do? Does it help in any way?

It's supposed to increase the friction so that the stick doesn't slip when you strike the ball. It's not that important if you're just hitting the ball in the center, as most casual players do. But if you're doing something fancy where you strike the ball off-center to put a spin on it, then making sure there's enough friction to initiate that spin can be important.
