is it have that goal is a problem?
I don't think everyone gambles just to get rich, there are many people who gambles just for fun with a small amount, so even if they loose it won't affect them much.
This is the most definite stand for most gamblers: Neutral. They spent a little bit of money and get some fun in return.
Then there are 0.001% who get rich and i guess around 1% who reach some serious debt.
You are right. Maybe not about the exact figures. But surely when it comes down to the people who win (very less) and the people who lose (a lot.).
Quite said it still happens these days.
