In my opinion, this is an impossible thing to happen, the casino went bankrupt because of the many players who won. And I think the casino has more control and rules for everyone who plays there.

With so many players winning, this will actually be the main attraction for the casino which will attract the attention of people to play there because they see a sizable chance of winning. When the casinos are more crowded, the profits will increase and I think those who own casinos are smarter than those who play.

One thing that can make a casino bankrupt is that there are no more people visiting and playing there which results in the casino losing money. So as long as people have an interest in gambling then casino venues will still exist and survive.
