But when someone started gambling they don't posses on their full control of emotional state. But I think rather than depend on luck we should focus on our skill. Sometimes we need to pull off , we need to stop gambling even after losses.

No one can maintain consecutive winning streak. But what we should maintain is that weekly or monthly positive PNL. Luck is a crucial factor to be play on gambling.  If we can control our emotions.  And if we can stop at the right time then we will have a positive PNL either at the end of the day or at the end of the month.

I even saw some gambler , when made some profit in their first 3/4board they quite and stay happy what he got for that day. This is self control .
