Maybe he was trying to say that the op is not a pro gambler because he is depending on his algorithms or methods/strategies . pro gamblers are already aware that there are no working strategies because gambling only based on luck . if they lucky they win and they save thier winnings , they use their winnings on other profitable and less riskier activities but they play still gambling on other times .
Poker is more like trading. You need to cut losses and know when to pass even if you already put tones of money on table. Here strategy might work because you don't play against casino where you have 47% probability of winning where casino has 53% (roulette example). In poker, you play against another player. Before looking into cards you and your opponents has exact the same probability of winning and this probability changes after each card you see. With bad cards you have low probability of winning that's why you should cut losses. And that's strategy that would work in poker.
