In gambling strategy then it isn’t sufficient to simply devise a way of playing that is fundamentally sound. It not only has to be fundamentally sound but it also needs to overcome any vigorish that may be up against you. For example we can look at biased wheels in roulette as a perfect analogy. Wheels can become biased but there are biases and biases and not only does a wheel have to be biased but it has to show enough of a bias to overcome the house edge.
This analogy is significant because it highlights the fact that many systems fail in gambling not because they are fundamentally unsound but because of the vigorish that is imposed on it from the casino or the gambling house. Poker is the same with table fees and rake and many would be successful poker players end up either not making money, losing money or not making enough to make the entire process financially viable above and beyond doing another line of work.
This process is the same for poker players because not only do you need to find a successful style but you also need to find a successful style that beats the rake and other overheads and also to find a successful style that allows you to earn an amount from the game that you deem to be financially viable. So any casino gambling strategy by sheer definition has many obstacles for it to overcome before it can start down the road to making money.
