I don't believe in perfect strategy in gambling, by the end of the day your luck will decide if you win or not. House edge and strategy can be a factor, but overall luck is a big part in playing in casinos
You, like many, don't seem to understand the difference between short term and long term gambling.
In the short term you can have positive results. Go to the casino with $200 and come out with $800, for example. But in the long term the HE is everything, the more times you play, the larger the numerical sample, the closer your actual results will be to the expected mathematical results, and these always consist of a net loss.
