Ways to pass parameters to c# methods?

Question

C++ / C#

studied the parameters of the methods, now I have a question about passing using ref, out.
As I understand it, ref can take data from a variable, and then transfer the processed data to the same variable, and this variable will change its value to the one that came from ref
But out does not take values ​​from a variable, but must be initialized in its own method, and after processing this value, transfers it to a variable and the variable is assigned the value received from out
I apologize if I did not explain clearly, I think that the picture will be clearer
