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.
There are few people that can benefit and profit from gambling, poker player vs player or sport betting but only a few like everything in life, its hard and not recommended, some people think they can do it as well but in reality they cant, at least most of them wont be able to.
But there is people winning millions through gambling
