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.
One thing we should know that is in sports is that irrespective of the type of sports involved, there is a winner and there is always a loser. Strategies sometimes do not work and you would believe or agree with me that there are a million and one strategies in the world that most gamblers use but I have this belief that when your luck shines on you, you will win but if otherwise, nothing for you but if a constant use of strategies is worth a small penny, then it is nice you keep it up and also put into use your instinct but be very cautiously.
