Uhmm I think it's not possible, not even for a newly opened casino because the chances are very low and even if happens it won't take when long before they recover their lose,
In fact there were some cases which proves that you are wrong because there were some bankrupted casinos but of course the reason is not only because of player's big win.
A new casino with less experienced owner might be bankrupted because of wrong management for the bankroll.
Although the chance for casinos to get bankrupt due to big wins by player is so small but chance is still a chance that may happen.
To avoid this, casino need to have proper bankroll management which is the most crucial part of the casino.
