So here the question would be whether it is possible to understand how
a trim tab works without ever having flown an aircraft.

I have flown in DA-20 and Tomahawk, but I do not think actual flight
would have been necessary to understand how trim tab works.

Knowing how a trim tab works isn't necessary for flying. The pilot
needs to know is how to use trim.
