The probability is 1 to none,  or should I say very slim and this is because gambling is an addiction,  one that's hard to break. 

There have been research of people who got substantial amounts from sports betting or any betting,  but kept going back in the hopes of winning higher amounts until the entire money won was sqandered. 

On a personal level,  there have been friends who have become impoverished due to sports betting. 

It is possible to become rich from sports betting,  but only if you are strong enough to walk away when you finally hit it big (an occurrence which seldom happens anyways).
