Gambling casinos do not let us gamble to win, but for them to take advantage on our funds and make them profitable. So I don’t believe that they will provide patterns for us, instead everything is already controlled by the gambling operators before we start gambling in their platforms. That’s how unfair gambling is. But we fail to see it at times we won, instead that creates more motivation for us that we can actually take advantage in gambling by creating some patterns. However, in the end, it’s always certain that casinos have still won back all our profits, because of the constant edge that they have over their players.
I think you are using the wrong words here, it is not like they don't let you win, or there are gambling operators who are controlling everything. Casinos are a business, and like any other business, they need money to run the business, hence the business model is built in such a way that it favors the platform more than the gamblers.
You can call it unfair or whatever, but there is nothing that is hidden from you or anyone who gambles, the house never says that they don't have an edge over you, they even let you know the house edge percentage for each game.
