It is almost impossible to count the card with 8 decks, so I don't think there is an advantage to waste time with live BJ games. Evolution gaming provider have a lots of live BJ tables and few Youtubers have tried to use card counting, as expected they busted after 3 hours of consecutive losses. If there was an big edge, the other pro gamblers have tried and shared the results with us. I don't see any reason to learn the card counting with advanced math skills.
A legendary can make it but no one has that skill and yes, that is very impossible.
I pressume such a trick won't actually work this time and I don't think either that casinos will take that advantage as well over their players.
Winning from this game will depend on luck and skill, not by counting it. It for sure casinos have some knowledge about this and they have already anticipating such a thing.
