What is the difference between MATIC and pol?

Excuse me, could you please clarify the difference between MATIC and POL for me? As I understand, they are both cryptocurrencies, but I'm not sure what sets them apart from each other. MATIC, being a token on the Polygon network, seems to focus on scalability and reducing transaction fees for the Ethereum blockchain. On the other hand, POL, which I'm less familiar with, seems to have its own unique set of features and use cases. Could you elaborate on the key differences between these two cryptocurrencies, and how they might appeal to different types of investors or users?
