Online poker is a myth furthermore Bitcoin casino poker is a bluff. Poker is a skill and behavior-based game, without the partner being physically present it is hard to call it poker. I do not believe in them and that is why I avoid playing online.
That's what I used to think too before I started to play poker online myself, and before I did a thorough research on the current top poker players. Now, when I read your comment, I'm inclined to think that your vision of poker is formed by movies and TV shows. When your opponent is physically present, you can win if you are good in reading their body language, right? Wrong.
Although it is very likely that being skillful in reading their facial expressions you would win against a 9-year-old, I can guarantee that you would have absolutely no advantage over an adult poker player in that regard.
There are tons of proofs that current best poker players are also good in online games. And whatever gives them that advantage, it's not the ability to "read" their opponent.
Regarding the OP's question I've voted "No, it doesn't". But I would't play in a casino where rake is over 6%
I'm not a poker player myself (as a child I couldn't grasp its main idea, though it was probably the fault of those who tried to teach me it), so I can't comment on this in a constructive way. However, I also tend to think that people overestimate their capacity for reading the body language and facial expressions here as this idea seems to be coming mostly from the movies. Billions comes to mind instantly but there are probably a lot of other films "featuring" poker, and in a totally misguiding way (like they do with casinos in general)
I corrected the poll a little (without changing its major theme)
