But let's assume 10% of the players do get greedy and try to win back everything and fail, then that means the casino will be in profits from those 10%. Of course we can assume as well that there would be players the profit from the casino, but theoretically it would still be hard to defeat the casino with the limits in place.
Then, in this case, you are assuming that the variance is in the casino's favor. Expected value changes not based on the bet limits, nor the strategy. You are
assuming that the casino has profited off players to prove that the casino is profitable. That is begging the question and is invalid.
Expected value is absolute.
Mathematically it is absolute and in a perfect scenario it will happen. But the fact is that it does not put into equation human emotions and other factors that greatly will change the outcome of the bets in the whole scenario. Indeed that 0% house edge will not be as profitable as the ones with house edge, but I am just disputing the argument that there is still a chance these kinds of casinos can exist and make a profit.
