Yes, and no.

Propellers do have an airfoil profile in order to push air. But that does not make them a wing. Wings give lift, propellers give "push", or thrust.

Helicopter rotors are a lot more complex than just a propeller aimed up. They have lots of controls to stabilize the rotors and adjust the blade angles to provide the controlled lift, to steer, etc.

Look, we're talking about technical terminology as precise as "force", "acceleration", or "theory". "Thrust" has a specific meaning - the propulsion of the plane. If you want to talk about other pushes on different parts of the plane, refer to them as forces. It's the terminology of physics.
