In my opinion, in the end, the casino still wins no matter how good you think the strategy is.
Talking about strategy, I believe that your strategy only looks good when you use it at the right time, meaning luck is still involved in it or you could say your strategy only works when luck comes at the right time.
Previously, I had tried several strategies but in the end it turned out that the strategy that worked in the past turned out to be completely useless at a different time.
Having good strategies is not a guarantee that you can rely on, but it is still Good to have your strategy but do not be carried away and think your strategy can give you what you want. Every strategy rely's on work, but it doesn't mean gambler should not try whatever strategy they may have.
Strategy can't do anything about the uncertainty in gambling, gamblers needs to to take note about this, and to know winning is by luck and every game remains unpredictable irrespective of the strategy you may have at hand.
