You probably know me if you know me at all.

You probably know me if you know me at all. (my bold, Yo-Yo Ma)
What does the quoted sentence mean?

Since you didn't provide any context, I had to search for it myself:

You probably know me, if you know me at all, as someone who does this. And I've done it for 60 years, so I should be getting it right by now.

When world-renowned cellist Yo-Yo Ma says the word this, he points at his cello. Here's a link to the video: https://www.masterclass.com/classes...ection/chapters/meet-your-instructor-yo-yo-ma

Did you really not understand what he meant, sitifan? Why didn't you give us the full context?

I did not fully understand the sentence I quoted. I heard the sentence from a YouTube commercial. I didn't know it was not a full sentence.

Do you understand it now?

Do you understand it now?

Yes. Thank you very much.
