Briefly describes how poor people earn a living in gambling way

Ambling doesn’t really do anything for me personally because I am a risk-averse person and so the appeal of casinos eludes me. But once the initial crowds die out, I may go to the casino to check out the place but not to gamble, except perhaps for a few hands of blackjack. Over the last five years I attended a couple of education conferences, one in Las Vegas and the other in Biloxi, Mississippi, that were held in a casinos so naturally I visited those floors in the night to see what it was like.
