In Poker, the Ace is the highest card and the 2 card (Deuce) is the lowest. However, the Ace can also be used as a low card, with the value of 1.

The short answer is yes  poker still falls under the category of gambling, despite its status as a game of skill. Consider the Merriam-Webster Dictionary definition of gambling: Gambling  the practice or activity of betting; the practice of risking money or other stakes in a game or bet.
