Because it does not require energy. That's why it is a form of passive transport. A spontaneous process can be defined as any process that does not require an input of energy to occur.

Brownian motion at the origin of diffusion is governed by temperature. For liquid or vapor this movement increases with temperature and is called thermal agitation. As soon as the temperature is above 0° kelvin, you have diffusion

It is driven by entropy. A system with the solutes concentrated in one area is more "organized" than a system in which the solutes are dispersed.
