2 things.
To Mr BJ.Mr J did not say you can't win at gambling.It seems the very opposite is the case as he professes to be financially dependant on his ability to win at Gambling.
He said you can't win long term at roulette.
Know the difference!

And Fernando,I think people who can control themselves and treat Gambling as entertainment and therapy,are the real winners.Regardless of whether they actually are profitting financially.
