I also think that vault could bring in some profit as well if wolf.bet really wants to go to that route for more money. Think about it as a bankroll for the casino, investment from the people, you can either make it a yearly thing that will give people a fixed amount of profit as long as they keep it there, or maybe it could be simply just bankrolling the casino and making a profit when casino makes a profit or losing when casino loses, both has advantages and disadvantages for both casino and the investors.

I don't know if wolf.bet needs money but considering they have dropped the prize from 1000 dollars to 500 dollars, I would say it is quite possible that they could actually take advantage of that money as well and work with it to get wolf.bet bigger as well.
