Which casino was this you played in?
The dealers in the live casinos are live, actually I have played texas hold'em poker with bitcoins where you have to guess which hand will win on the river. It's pretty entertaining and the girls have monitors to see your moves like check, rises. etc.
I am not sure what casino he played it on. But the only one I have seen so far offering live poker is :
https://bitcasino.io/ . But these sites are much more fishy than the ones of live roulette.
That is why live dealings in online casinos can be manipulated easily. You will not have no way of checking your bet so "provably fair" is like empty promise in that case. If you want 'real' experience you need to visit real establishment.
Yes, I guess thats the way things usually are on these poker games. But again, they aren't like your normal poker, as no one folds in those hands. Cards are dealt till the river and you can bet on each street.
So basically its pure gambling and no skill in that form of poker anyways.
