If I remember well: in normal condition the lift come 2/3 from the top of the wing and 1/3 from the bottom of wing.

So the depression above the wing is indeed "pulling up" the wing more than the surpression below the wing is pushing up the wing.

No, a vacuum never "pulls". The pressure on the other side of the object pushes it.
