At what point are you just a gambler?

[Aequitas58]

That's called a "problem."

I may be nieve here, but are there professonal blackjack players? What about professonal roulette players? Craps? Sure, a lot of money can be won playing these games (even if you eat the -EV) but don't most of these people have regular jobs - opposed to the overwhelming number of pro proker players?
