After working over the worst cases available through public data in both roulette and Baccarat, I can confirm for sure that one who can survive through the worst possible and recover its losses too in average case thereafter(without expecting clumping or compensatory wins) is an ultimate winner and only such person can be a winner in the long run in a random game.

Rest of the magicians who can use physics based advantage play or have power of precognition to guess how to win more flat bet are Gods of gambling themselves. Nothing beats them except casino bouncers.
