True, but this is hardly a college lecture, so for the fun of the game I felt like my answer was “close enough”. I feel like it definitely makes sense to be pedantic in most places, but a discussion of favorite dinosaurs feels a but much.

Also dinosaur has become more of a colloquial term over the years as well, which has bent its popular definition to simply include many prehistoric non-mammal animals. However you are right in the paleontological definition.
