This means that there is no perfect strategy to winning. Even if we are gambling for 10 years, 20 years, and more, this won't make us safe and winnable; this won't change the odds as we still lose. That is why we could say that winning is luck, not because we use this strategy or our instinct. So we have to stop assuming that the use of our instinct is better or our strategy (and vice versa) because none of them guarantee winnings. And much more in believing other strategies and copying it, as the results may differ.
Indeed there is no guaranteed strategy of winning in gambling. No matter how hard you try to come up with new strategies, trust me it has already been tried out by another gambler so the best approach to gamble is to gamble with what you can afford to loss because there are more losses than wins in this line of game and only the discipline can gamble for a long period of time without getting addicted. The last thing any gamble can wish for emself is addicted especially when it come with several irresponsible decisions.
