I don't think there is people richs from gambling. Even if the gamblers win big amounts they will start gambling again and can lose it in seconds, because gambling is addictive as known
Yes true that no one is really experienced victory and become rich in gambling. People can defeat more after a victory. Gambling is a place to play not to make a profit with certainty.
Yeah it is true, I think the benefit in gambling only some people and all those who benefit in gambling has only a very short time of victory and the wealth they get can only be enjoyed within a short time, because they spend all the wealth to do gambling.
