While it certainly is a fact there are poker professionals making a living playing poker...and some a VERY good living. Blackjack card counters can try to make a living but the casino industry has done just about everything possible to make their play impossible...and miserable. I will assume there are a few sports handicappers out there that are plying their trade. Very, very few. Craps, roulette, slots....no chance IMO. I can try a grind play and in fact my play is essentially a grind play. I can play 5 days a week if I really wanted, stick to the lowest house edge on craps...just look for very small gains and exit. It's not going to work, IMO. I could go the other route with a full 99% martingale and somehow hope, pray, rabbits foot, etc. or the man above excludes that 1% loser from my play. In any case, I don't believe it's possible to "make regular bank" in craps. I can certainly keep it close...and I do. But that's about it. A martingale wil ensure regular bank but the obvious caveat applies. I could see certain people playing 10-12-15 times a year and having a net ahead year. But ultimately I think that is just a luck of the draw. A willingness to "chase" might even help in this case. Where comps enter in is a different story and with enough buy in and play...A big player could probably squeeze out some decent comps. But, dinners, rooms, plane rides, swag aren't paying the cell phone bill. You would need cash from them. The thing they least like to part with. Am I surprised a proclaimed DI who moved here...has to work a regular job out here? Of course not.
