What is the difference between Creo and Creo Parametric?

Excuse me, could you please elaborate on the distinction between Creo and Creo Parametric? As a professional in the cryptocurrency and finance field, I understand that software tools like these are essential in many industries, but I'm curious about their specific differences. Are they two separate products, or does one build upon the other? Is there a particular industry or use case where one might be more suitable than the other? I'd appreciate any insight you could provide.
