Difference in "mkto-unsubscribe" link and "Unsubscribe" metric numbers

[Parvej_Ahemad]

After data download from Marketo, I have noticed that "mkto-unsubscribe" link clicks are much more higher than the "Unsubscribe" metric numbers, I want to understand which is the correct unsubscribe number and what is the difference between these two.

I'm not sure how to change it discussion to a question hence created a new question. Please help on that.
