It is gambling, beginners can be lucky because experienced people can also go for the best matches and lose.
And not only that, because in most casues, an experience gambler will tend to over-analyze, and at that such end up missing the golden opportunity simply because he never believe in it, unlike a newbie gambler who may pick at random for the first time and gets lucky. But not everyon always get the "beginners luck", which is why in most scenario, the best idea will be to walk away with your first winning, rather than keep playing and lose it all
When you are just starting to gamble and turns out to be a win then it would really be motivate you out on playing even more until you do bust up all of those winnings.You would really be making more deposit because
you would really be tending to chase up those losses and this is where that common cycle would be starting on where a certain individual whether they would be completely on stopping gambling to avoid further loss
or would be tending to chase up on what they had lost and would be trying out to recover those which might be ending up for them to get addicted and would cause out much more trouble later on.
This is why its really important on making yourself that fully aware on what you are dealing with and act according into your will on which one is really better.
