Does credit mean I owe money?

Hello there, I'm curious about the concept of credit. I've heard it mentioned in the context of finance and cryptocurrency, but I'm not entirely sure what it entails. Specifically, I'm wondering if the term 'credit' simply means that I owe money to someone or if there's more to it. Could you please elaborate on the meaning of credit and how it relates to financial transactions and investments, including those involving cryptocurrencies? Thank you in advance for your insights.
