Our brain is in our control, what we are going to do comes from us - emotions/feelings, and wants to do. But if we talk about gambling, it is a different thing knowing that we are not controlling it so we couldn't say that if we wanted to win, we win. No, because gambling is also controlled by others which is beyond our control. This means that whatever their plan (owner) will also be the result and this is why players often lose their money rather than winning.
