In casino games, losses are almost certain to come with it, but there is no guarantee of winning, rather the chances of the lost are more than the chances of win, because a casino will never give you money from their own pocket,
I completely agree with what you say about casinos, for me it's a fact that things are like that, personally to know that and mature it I had to go through many processes, because since we are newbies we see things from another point of view, we think that those things are not going to happen to us and that is why we make so many mistakes, always before playing we must be clear about what we are facing.
The casino are on the upper hand why we the players are on the lower hand that’s how the system is built they need to continue being in business which is while gambling is programmed to be a game of probability, betting also falls under that same category we can only try as much as we can to secure winning but we should always get our minds ready that winning is what we will experience more.
