Crawled seems to mean "requested" - so that would include even 404 responses. Unfortunately, clicking on the "learn more" link results in a Page Not Found message, so we can't really tell, officially at least.
I can tell you that almost every site I check also has impossible numbers here unless 404 responses are part of the picture. However, your number is a lot more impossible than the ones that I see.
