What about those people from MIT that figured out a system to win at Blackjack? Surely they would have not eventually lost money, right?
Don't be dense. Once you start counting cards, it's deterministic. That's why the blacklist you from casinos. Poker is a skill and if acquired you can earn money at it, too. But I don't have the time or desire. Slots, Roulette (fun bets on black and red are reasonable, what is it, a 47% chance of a win?), craps, etc., are fun pursuits but should be recognized for what they are. Lottery tickets are a tax on the uninformed.
