Gambling sites know all the Strategies which can make the customer win, so they have already the control in place.
You can't general this, although some gambling platform employs researcher to research on new gambling strategy and study then to help improve their platform, not all gambling platform can afford that especially the new ones and beside new strategy are coming out so the gambling platform can't know all the wining strategy out there but they could be aware of majority.
The gambling platform certainly has an AI system that can learn every strategy from gamblers. This system does not recognize the new strategy or the majority strategy used, each bet is played, the system will record each of these betting strategies. I don't know why I think like that, but I am very sure that they have control over all gambling strategies.
