To achieve this, the person has to be aware of and Accept that they have taken unnecessary risks and that these risks do not correspond to the outcome, If the player understands this, then everything is simpler, but if it is a person who does not recognize it, then they will continue in that infinite cycle where only that person suffers.
There are so many gamblers still stuck on this cycle. Then there are people who understand that they are losing good amount of money but cannot control themselves from playing more. Hence it is important to identify the problem and keep aside the emotions associated with it while still controlling the gambling habit.
Big analyst or big bettor does not mean a thing unless the person wins. The ones who eventually understand how casinos work will come aside from casinos and make money from alternate methods like promotions and podcasts to selling books on how to make money. Its a facade they have to put up to cover their debts.
