ELI5: Instead of trying to be emotionless, why poker players don't exaggerate fake emotions to confuse the opponent?

Doing nothing all the time gives away nothing.  Exaggerating fake emotions is you doing something, doing something can be tracked.  In the case of poker where there are so many hands, you trying to mimic exaggerated movements will eventually lead to inaccuracies where your "tells" will become known.  This technique may work while playing with friends but pros will be able to pick up on things.
