The OP wants to find a winning strategy and it doesn't ask about certain games or casinos. From this I conclude that the OP does not have any information on this topic and he is looking for ways to make money.
Here, the correct advice was given in relation to the fact that gambling regularly does not earn money.
By the way, you are right. In fact, there is no specific strategy on how to win at the casino. If the OP created a topic for a specific game, for example, Dice or Roulette or Slots, then probably he was prompted by several strategies with which he could work and understand how these games work. Therefore, his initial question a priori will not bring the answer he needs.
