If there are 100 people that have not gambled before but about to start. If they tell them to gamble and people are seeing them while gambling. Not all of them would first win. Some people will win while some people will lose. I know someone that gambled for the first time that lost the game immediately and he told me he is no more gambling again.
That's the reality in gambling, some may lucky and win, while others have no chances of winning but lose them all. This is also a proof that luck can happen any time, not actually in the beginning. However, just because we often hear successful gambling stories at the start of their gambling career, this become a reason for some gamblers to believe that beginner's luck exists.
Not all beginners can win in the first time they gamble. But we admit that some beginners can win so that will attract them to keep playing gambling in the other days. They should know that even if they are beginners in gambling, that doesn't make them win easily because that will depend on their luck. If they don't have luck, they will not win anything and only lose their money. If they push themselves to keep playing gambling, they must be ready with the lose that can comes anytime.
