If I have the money to build my own casino, I will also play safe by limiting how much a gambler can use to bet at a time so that they don't get too lucky and earn too much than I can afford to pay them. This is why almost all the casino games we are playing have limits for gamblers to reduce the possibility of excessive winning. As a gambler, I don't wait to brocme greedy using very high stake to bet at a time.
The possibility of gamblers even reaching that maximum winning rate is always very low, but the casino has to set it after all, as they don't want to take chances, and the limit which they set for all players should be to moderate the winning amount, not to exceed their budgeted reserve for winning payouts, any player who tries to bet or stake a game with the exact maximum which the casino set is trying to be greedy and at same time will end up losing it without winning what they targeted.
