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.
There are some persons who actually did had a very terrible gambling beginning, they didn't get to experience the beginners luck syndrome at the beginning of their gambling career and that doesn't mean they will continue loosing, along the line, some later became successful gambling so it's not going to happen following same pattern for everyone, it's only going to happen in a pattern that will probably to relatable to each individual even if in some cases there's this uniform luck for a group, it still doesn't put out the occasional and known disparities.
