I believe in beginner's luck which comes to beginners when they are just starting to play gambling. But after playing for a long time, the beginner's luck will disappear because they will experience loss, and some even experience losing streaks.
You can first gamble and win. You can first gamble and lose. I have friends that first gamble and lost. I still even remember a friend of mine that gambled the first time and lost and said he will not gamble again and he is not gambling again.
Maybe after they get that beginner's luck, they should give up gambling for a while and not gamble. But most people who become novice gamblers instead play gambling again, which makes them experience loss at gambling. And many of them are getting used to this loss by continuing to gamble.
Making money is enjoyable for everyone, people are ready to devote time and themselves on what is giving them money, but many newbie gamblers do not know that gambling is not working like that, that it is just luck that they first have when they gamble. It will sweet them as they have the luck but later the opposite will start to occur and it may later become a bad time for them.
