Everyone who gambles has experienced losses, but not major losses such as losing large sums of money or selling assets like houses or other things just to gamble.
I have never experienced the worst loss in gambling,
If might not have witnessed it or read about it but obviously there are people who must have had a terrible case of gambling losses, have you not read a story that was told on this forum about a man that got arrested because he used the money that was meant for his office committee to gamble and he lost it. I have also said it before that someone (an engineer at a site) used the money he was given to for gambling. Actually the money was for a job but he was greedy and wanted to double the money but he lost it and ran away.
If you have not experienced a bad lose, it means you are only and always gambling with the amount you can afford to lose, no big risk.
