It's gambling in the same sense poker is gambling. There is skill involved in both, but if you are in it for the short term you will face variance and could lose money regardless of skill. If you have skill AND play for a long time, then the variance is lowered and it is positive EV. It is in the site's best interests to actually decrease the skill portion and increase the luck portion. The main reason is because new user's will try it out a few times, lose all their money to the site's sharks and say they cannot win and give up.
