Good for you that you have the control, but despite having the control, that would not change the reality that we will just loss in gambling.
Having control back in your own hands is the first sign that you are turning back the table on your addiction. This is a good sign for a person who wants to get rid of their addiction and start getting involved in more fruitful work.
Nothing is easy, that's the norms in gambling, one has to be discipline not to win, but just to minimize his loses and not be able to loss beyond his budget.
I think a person who is able to be control and have discipline would not gamble at all. They would stop it entirely and depend on other sources of earnings or get a proper job and lead a happy and safe life away from all the debts and money lost. Discipline is something that is lacking among all gamblers, but hey, thats what made them gamblers in the first place and its going to keep it like that.

Even if you have control on yourself or not but you will still have the same chances to win and lose in the same luck based game which you have started and your opponents will then increase your chances of losing much more. Furthermore, if your opponents are more advanced in the game then your chances of winning are negligible but make sure you improve your knowledge and use strategies to win the game.
