Well whichever guide online is there or whichever expert tells that he can make 1000's of $$ from gambling there is always a chance of losing remember that. No guide can actually help you win a gambling match as it is luck. So even if someone made 10000$ from gambling and he says even you can do it well that's not possible as gambling is pure luck. I would recommend people to stay away from gambling as it can cost you millions and it is too risky also
