In the end you always lose gambling, the casino's did not get built losing money. All they need is 51% chance to win, and you are screwed. Only gamble what you are prepared to lose, or even better, only gamble with your winnings. Never believe you can gamble yourself out of a hole "with one lucky hand". Also, the closer you get to the center of the casino, the faster you will go broke. They are built with a purpose, winners on the outside to draw people in, once your in the center, empty your pockets.
