Does Mockito mocks classes and functions using Reflection?

I've been trying to understand how Mockito mocking works. I've read various responses and there seems to be a conflicting argument whether Mockito uses reflection internally or not.

Here, it clearly says that mockito does not use Reflection: https://stackoverflow.com/questions/15970810/using-mockito-to-mock-methods-by-reflection#:~:text=Mockito%20is%20a%20really%20well,easy%20to%20read%20and%20understand.

On the other hand, the most popular tutorial website says otherwise in the very first line under Mockito: https://www.tutorialspoint.com/mockito/mockito_overview.htm

I'm slightly confused with what's true about mocking with Mockito.
