you can win a lot of money,
It depends very much on your luck and where you play.
If you have a good strategy you are more likely to win.
Indeed. If you were born to be lucky, then earn a lot of money by gambling is possible.
But there is no such thing as "good strategy" in gambling.
the point is lucky, if you have a very good plan in gambling but you're not lucky then you will lose money and not produce anything
