That might help, but only for a short time. In the end, it is bound to fail. In fact, in the first place, we agree that emotions come up no matter how much control we try to exert, and that's normal because we're humans. So, no matter what we do or what strategy we use, no one can guarantee that it will actually work.
Strategy in gambling only helps when it is applied in financial management or our playing limits but if it is to pursue winning it can be said to be impossible because all strategies only work for a moment and if continued for the long term it will only lead to losses. And you are right as humans emotions will control us even though we try to control it even in a winning situation we can be provoked into continuing to play especially losing is very likely to think about recovering losses
