I play poker a lot, and I know that this game is not entirely based on luck. But I also watch a lot of poker related videos on YouTube, and from those videos I've learned that even the professional poker players, who are considered the best in the world, lose pretty frequently because of bad luck. That's why I wouldn't recommend this occupation as a profession to anyone, luck is too much of a factor in it.
Only if you play video poker, ...
That's not poker, because in video poker you don't have an option to bluff.
Close, but still far from being real poker because poker bots can be easily outplayed by average poker players. (I'm not talking about AI poker bots, such as Libratus, because they cost millions, if not tens of millions, USD, and no gambling site can afford running them.)
This can perfectly be a real poker. I don't understand why you put all of them in the same sentence.
That's right, but have you, by any chance, wondered why did he lose all those all-ins? Bad luck, that's why. Imo he was doing the right thing going all-in all the time against a player who had much less chips than he did, but in the end he lost all his balance because of the bad luck. Luck is too much of a factor in poker to consider it as a profession.
