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.
Yes, it's the definition of gambling, we might have luck in our side or not. And most likely this is the same reason why everyone wants to gamble because we believed at the divine and that they will give us luck in the end. But in the end, not everyone has it, most of us lose and then the vicious cycle begins.
And sometimes we only need that one win and then we are hook up already, because of this beginners luck that we believed which obviously though is false mentality. But then again, that feeling of winning, it's really hard to resists as we want to experience that again about our first time and so that's where the cycle of gambling starts. So this beginner's luck could be curse after all.
