True.
Try flying a Cessna out of a snow covered airfield.
The nosegear will dig in and pulls the nose downwards increasing the negative angle of attack of the wing, building up drag big time. You never reached liftoff speed.
The only way out was to lift the nose out of the snow, accelerating on the mains only and flying out safely.

But again this has nothing to do with the origin of the thread: groundeffect.
