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.
Of a truth the possibility of the 100 new gamblers winning all at once, in same week are slim, but the truth remains that majority of them stand a higher chances of winning, provided they aren't listening to external factors, and act according to their instincts. External factors such as listening /taking advice from old gamblers, will hinder them from winning. But if they continue gambling for the first one month together, with their newbies mentalities, they are all going to win within the first one month. Although their winning won't come the same week, some will win this week, while others will win in subsequent weeks. I don't know how this usually happens, but somehow gambling has a way of rewarding new gamblers within the first week or month of trial. It happened to me and few of my guys that started gambling with me. But I have come to realise that too much experience and analysis in gambling is what makes gamblers lose bets very often.
