That is a crazy thread you have created there OP. I very much doubt anyone has become a billionaire threw gambling, well the type of gambling you are talking about because even if they did they would end up losing it.
I do enjoy some gambling but only that which requires some skill what will give you an edge, that is why I only play poker, but now and again I do bet on the football as I'm not a newbie to football.
Over all it has done neither destroyed or fixed my life because I won't let it, just play in moderation and have fun.
