From hustling pool at age nine, to making and blowing a fortune in his native Kentucky, Billy Walters has risked it all - and then some. Walters is telling his story in a new book: "Gambler: Secrets From a Life at Risk." Billy shares a few of his stories: developing the first computer-driven sports betting program, running an offshore book that bet games all over the world, doing prison time, working with Opportunity Village and much more.  Hosts: Jonathan Jossel, Gary Vickery
