Three could be a ballad...if....

One of my favorites is "The Twa Corbies", and it is only 5.

Most stories take a bit longer to flesh out, and ballads usually need a bit of development or we wonder what happened when....xxxx or yyyyy.

I think "Amelia Earhart" is a ballad of sorts...but one verse is commonly left out,(YouTube clip) making a 4 verse story into a strange 3 verse version.
