Yes! Gambling loses ang win. Theres ups and down too. I always win than lose. I experience that knowledge is more powerful than experience. The more you wise you are the more money you have.
Even with Knowledge and Experience, there is another factor which may completely make you lose or win and that is Fate or Luck. I have won some pretty good amount in the past but always felt the luck to be with me. Of course I have played with tactics and strategy. May be its different to every person.
