But isnt it only true when the forces are passing through the axis of rotation?

3 force passing through 1 point => net force in 1 direction
otherwise, at least 2 net force acting at 2 point => couple or turning force.

torque makes a object to ROTATE
if forces pass through one point only
that means the directions of forces are opposite to each other
so no rotation is found
