It's kinda both. A lot of the reason Rhino gets used is the Dragonfly plugin, which allows for generative systems style creation of geometry. There's really two layers of "parametric" here, the basic being that CAD tools are now parametric, basically meaning drawings you can revise as needed, and then the second being how design philosophy reacts to this sort of software as a new tool, particularly when coupled to constrained optimizers searching through design possibilities weighted by a creative input.
