When you are running on a treadmill, the thing that propels you is your feet pushing backwards on the treadmill.

When a plane is taking off, the thing that propels it is the jet engines pushing backwards on air.

When you are running on a treadmill you don’t move forward because the thing you are pushing on is moving the direction you are pushing, hence no force and thus you don’t move.

When a plane on a treadmill is taking off, the thing it is pushing on (the air) is stationary, hence force and thus the plane moves.
