When it comes to gambling self control matters alot , that's the reason most gamblers usually lose all their money due to lack of self-control, and this is usually common among newbies too , those that went into gambling with the mindset of getting rich quick with it , usually loss self-control inorder to hit the jackpot but at the end they normally endup with an opposite results (losses). We should always have good self-control whenever we gambling so that we can know when to continue or when to stop.
They lose control in gambling so they lose their money. If they can stick to limits their money, they will take care their money and will not lose too much money. Playing gambling needs luck although you have skills in certain gambling games so you must knows how to spends your money.
You can gets your luck in gambling but no one will know when their luck will come. If they just keeps gambling but with moderately, they will gets their luck someday and they will wins the games. But you must be patience and not use too much money for playing gambling.
If their minds thinks about getting rich from gambling, they must change their minds and not use gambling to getting rich but must search for the other ways. Winning the money in gambling is difficult and not as easy as we thinks so we don't have to force ourselves to try to wins. Lets our luck comes by itself.
Completely agree with you, most especially; the last phrase in your comment which says, "let's our luck come by itself" which in other words, we can say that the best way to really win in gambling is not to force ourselves into it, but allow the win to naturally come to us.
Chasing after wins, or in other words, chasing after what we have lost in a bid to recover it back is sure one to the very first steps in failing as a gambler, this often lead to gambling addiction which usually is the beginning of a life filled with troubles which arises from financial problems.
So, to really enjoy gambling, it's not necessary we play for fun at all times, but we must not try to force ourself to win, for in doing this, we may end up with loses we never did imagined, we must allow luck do it's things at all times.
