Why does 2+2 call poker gambling?

[Skallagrim]

If betting $10 with your buddies on who will get the best score at your Thursday night bowling game is gambling, so is poker.

If gambling is betting on a game of chance, poker is not gambling.

If it were not for the fact that the word "gambling" has some bad legal status, I wouldn't care whether you called it that or not.
