When in straight and level flight, the air flow through the rotor blades
of a gyrocopter is upward.


Yeah well there's a lot of empty space between those gyrocopter blades
for the air to blow through in an upward direction.

What you don't mention is that there's also downward component to that
airflow, when it impacts the gyrocopter blades and is knocked downward.
The air gets knocked downard, the blades get knocked upward, the
gyrocopter is attached to the blades, it gets held up in the air -- so
the magic is revealed once again as "downwash".


Nope
