As I mentioned above, if only the person or the gambler can have that kind of mindset it will add up the fun since they manage to win and use the money for business, if both are successful then financial stability plus enjoyment can be the take away from it, though it's not as easy as it is since most of the time gamblers will continue to play even they already have the chance of winning but instead they push for more and lose the money again.
If they don't also realize that chasing their losses could cause them to lose even more, they could actually lose a lot of money that they won't be able to afford. If the gambler has been successful in making a lot of money, they should stop gambling and leave the casino to enjoy their winnings by celebrating and resting for a while. Continuing to practice this can make them avoid chasing bigger wins and they will also not try to recover their losses if they experience defeat. If they have won a lot of money, they should think about what they should prepare for the winning money. They can't win big another day so they have to think about trying to make money elsewhere.
