I also agree with it, some people only win in the casino and dedicate it to continue betting and betting and I know real cases, where a person who bets in a physical casino betting house loses everything they win quickly and does not even they can enjoy, this is something that does not go only to the plan of greed but to another level,
There is always this natural tendency that a money which comes quickly always goes quickly the same way it came, if I'm not mistaken because that's one thing I have noticed about majority of money won as a result of gambling activities. I so much agree with what you just said above, that when some persons win a certain amount, they tend to dedicate half if not whole for betting with the aim they may get lucky just like the previous, but unfortunately sometimes ends up squandering the whole funds. Which is why most persons who won huge, can still go back to poverty in few months simply as a result of poor money management skills
Being so excited with huge amount of money that they've won the mindsets are being manipulated by gambling, I mean after enjoying that earnings out from the casino gambler thinks that they can just simply repeat it again and again, the fact that aside from those who are already experienced gamblers who understand the risk, most who of those who managed to win huge also lost it back.
You need to work well with handling or managing your money so you won't experience huge losses back and you may enjoy the money to establish business and be financially stable after.
