Even for a new casino, I doubt that they would easily get bankrupt just because of a gambler who will win a huge prize. For a start up casino, of course they could just put a certain amount or a prize pool that they can afford to give to the gamblers if they win.
Any potential winning rate placed by the casinos is base on what they can afford to give, that's why if you win a huge amount, they may request for your physical presence to be able to keep a track record of your winnings on their archive and celebrate your victory as well, you could imagine seing over hundred gamblers betting and hardly you find one winning out of them all, the more the casinos easily generate momey the fast they also give it out on winnings and maintenance.
But it won't be easy to win over the casino where they could end up getting bankrupt since you need to continuously win huge amounts.
There this common believe that tou can't expect everyday to be a Christmas day, we may be trying on several occasions but if the luck gives you the chance needed, you may have an occasional winning experience from using a casino, remember that this is not something byoubsee constantly.
Aside from algorithm, they can limit the amount a person can win for a day, to prevent losing too much.
If there are instances where a gambler keeps winning that casinos cannot pay him anymore, it's a rare case.
I think some casinos already have this, they have developed a system that monitors your highest winning limit pegged to a particular amount they can afford to give base on their own standings as well.
