The drag force can be affected by the velocity of the object relative to the fluid. Does that mean the wind affects the drag force, since it changes the velocity of air particles?

There's no reason it doesn't. In fact, as predicted by Newtonian and Special Relativity, there are pretty much identical situations.

Drag force depends on the velocity difference between fluid and object. It doesn't matter which is moving. Planes and cars are tested in wind tunnels, where the air is moving instead of the vehicle.
