It’s really not. The longer travel of the air over the top of the wing creates an area of lower pressure than the air flowing under the wing, effectively “pushing” the wing upward.
That is true, yes. The shape of the wing creates a pressure gradient, causing the wing to lift up and deflect the air down. Newton’s law requires an equal and opposite force.
This spoon in the sink illustration really shows this:
