To me, spam has nothing to do with the length of the comment, it's what is intended. If it's there to just bring attention to something else like others voiced here already, that's spam. It has nothing to do with the content and is just advertising.
A short "good video" comment isnt spam, it's just not the most engaging comment. I would never report a comment like that though or say no to them.

Length doesn't matter to me as well.
Thank you friend for your time and opinion.
Have a good day from my side.
