No gambling strategy can give you 100% winning ratio. This in most cases will just help to secure more winning. The funniest thing about this strategy is that what works for me may not work for you. Having one own strategy and working with it is the best when it comes to gambling.
Gambling also involves luck, I agree with you that the strategy used by others is not necessarily good for me. it is better to use your own strategy to win or lose there is satisfaction because you have tried.
That no one succeeds or becomes rich because of gambling or because of the strategy he uses, if there is 1 in 1000 because of the luck factor.
The strategy I use is to gamble at a time when my mind is happy and calm, even if I lose, it doesn't make me frustrated.
