Is MATIC 20 and Polygon the same?

Could you clarify for me, are MATIC 20 and Polygon interchangeable terms or are they referring to separate entities within the cryptocurrency and blockchain space? I'm a bit confused as to whether they represent the same thing or if they have distinct roles and purposes. If they are not the same, could you elaborate on the differences between the two and how they are related, if at all? Thank you for your clarification.
