Definition of spoiler: A description of an important plot development in a television show, movie, or book which if previously known may reduce surprise or suspense for a first-time viewer or reader.

So yes, definitively speaking, revealing a brief sentence about the ending is a spoiler, granted, it's not going to "ruin" the core surprise or the "emotional journey" of the movie.
