Simply put, its impossible, you can not predict the outcome of a gamble, that is part of gambling, this is indeed absurd in its core, you will never be able to not lose, losing is a part of gambling that it's inherent, and you should not pretend to change the laws of physics, which include an unavoidable % of losing in bets.
He's right, gambling is gambling. You can never control the outcome of a game. It will always be out of your control. Hence, being independent of your control, then you will never be able to "gamble with no lose". It's mathematically impossible to win every game you play on gambling. Well, technically it is possible but the chances are so small that you can consider it as impossible.
