The fluid pressure gradient in the lymphatic system is established by two things. The first is movements caused by breathing, and the second is contractions of the skeletal muscles.

Why don't winds simply flow down a pressure gradient?

Usually a fluid gradient refers to the pressure gradient in any kind of fluid. It is a quantity that shows which direction and how fast the pressure changes around a location.
It is a difference in pressure
no gas flow is equal to pressure gradient over resistance
True
Pressure gradient is the rate of pressure change as you change position, not just the difference between the lowest pressure and the highest pressure, but how great (or small) the physical distance between them. Since it the pressure difference that make air flow (wind) the greater the pressure gradient, the greater the wind.
