There are many forms of poker
Poker" is not like "chess" where a clear picture appears from just one word. Besides "video poker" and "poker runs", which hijack the word into unrelated territory, there are many forms of poker. These different games feature some cards face-up, some face-down; sometimes you get more cards all at the same time, sometimes you get one at a time; sometimes you share pots; sometimes you try to make high hands, sometimes you try to make low. Different poker games have many different features.
It should not be surprising then that different poker games value different skills, and even have different relationships with the concept of "skill".
What's more, poker players will choose different high-tech poker products with different poker games, some will choose marked cards with infrared contact lenses, some will choose scanning system, some will choose IR camera and IR marked cards etc.
