This is because they are not under any potential difference in the system which can make them move rapidly & result an induced current.

Because their direction of movement is so random,
and their charges are cancelled because of the opposing directions.
Think of it as two people pulling the same thing from a lot of direction
with equal for. Would that object move? No.
Similarly unless all the electrons don't flow in same direction, their is no current. And no electricity.
So how do we make them flow in same direction?
We make them move in the same direction, how's that? Simple, just by turning ON a switch ;)
