What did GZA mean in this verse. I could never really understand it.

"The banks a G, all CREAM downs a bet
Money feed good, opposites off the set"

The first line is a refrence to the Cee-Loo game, right? Bank is the person who give instruction to other players of how big the ante will be. So here it's $1000 (a G).

But what does the second line mean? Is he saying about his clique (set) or does "set" mean something different here?
