Yes playing is a party of gambling activity. Everything about life is gambling, even Poker. It is all matters with anticipating outcome of winning that you do by chance. Pokers require a skill, a very serious one. Poker is a form of gambling and a game of skill as well. Actually almost every competition is gambling.
Not everything in life is gambling, you can't call picking a banana a gambling, you can't call harvesting as gambling, they are all part of survival, but, if you are putting a bet in it, or there is risking involved... For example, you want to pick banana, but you want to compete with others or you dare them that you could pick certain number of banana in an hour with the bet of $1, then that's gambling. But anyway, poker, if you are playing against yourself in real life, that's not gambling, and in online you are playing with bot and no money involve, that's not gambling.
