That's exactly what I was thinking.
If your starting point is luck, you may win, but it will more often that you will lose. So be it short therm or long therm you will lose more then you win, since you can't predict your luck and thus wage higher bets, alas you have to make strategic bets and even then your average balance will be negative, unless offcourse if you play with a winning strategy, which I doubt exist.
Yes i agree this some times our luck will help us to make profit but many times our greedines will smash everything and make us to empty our wallet. This is correct ?. I think many gamblers will face this experience daily. I can not say that long run profit in gambling is not possible there are some people can make this. But this type of people we see very few in gambling.
