Is Polygon and Polygon Matic the same?

Could you clarify for me if Polygon and Polygon Matic are indeed the same thing? I've been reading a lot about blockchain technology and cryptocurrencies, and I've come across these two terms quite frequently. They seem to be used interchangeably in some contexts, but I'm not entirely sure if they refer to the exact same concept. Could you possibly explain the relationship between them, if any, and clarify any differences that might exist? It would greatly assist me in better understanding the intricacies of this fascinating field.
