15 percent of jack shit

A waiter Monty asks another waiter Dean about his table:

Dean: Couple of hicks. Yeah, but the check total's $63, so even if they tip 15 percent I should make 10 bucks.
Monty: You're a bastard. So far I've made 15 percent of jack shit.

What is the meaning of "jack shit" in waiter's language?
Does it mean Nothing at all?
