I allways presumed they used a CSF -- pretty sure I have seen them in those pictures on the casino homepage of "our live webcam blackjack" etc.

If they werent using a CSF, I think you could make a profit. Essentially you would use a complex team-based approach (potentially spread across different skins), where it is very difficult to detect becasue no single agent would be changing their betsize in accordance with the count.
