This may not be a clever answer, but even you push it over, the wheel’s weight rest more on the right side, increasing the friction on the right and decreasing the friction on the left. This alone would cause a wheel to turn.
Frictional interactions with the ground do matter and are where a lot of the angular momentum “goes” between the initial and final state of the turn.
Without friction acting as you describe as well as bleeding angular momentum, the gyroscopic forces would just cause tumbling and not turning.
The interaction with the ground and with gravity are key features of this picture interacting with the conservation of angular momentum to produce the final observed result.

I think it’s clever and I like it.

So, not in a vacuum?
They were referring to friction between the wheel and the ground. Air friction has nothing to do with that.
