Damn, rich people that can waste too much money just to gamble and lose it. It is not that OP literally let it lost but he already lost so it is a huge amount that we are talking about within just a few days or months just by playing gambling.
Anyway, average people will secure their needs first before they take a risk of playing gambling.
It shouldn't be only the "average" people who keeps track of their money. Every people should secure their needs first and abstain themselves from gambling unless they can afford to lose and just for pure entertainment and adrenaline rush. And a rich people "can never" waste too much money. This is how they end up being broke, no matter how rich they are.
