The humor might come from the way the story is told. If it has a lot of vivid descriptions of funny expressions or sounds. Like in a story where a parrot imitates a person's sneeze in a very exaggerated way. It makes the story more engaging and funny.
The unexpected twists usually make it funny. For example, if a character is supposed to be very serious all the time but suddenly does something completely silly like dancing in the rain without any reason. That kind of deviation from the norm can be a great source of humor.
Well, given that IMDb is focused on movies and television, it's a movie. The title 'It's Kind of a Funny Story' has the feel of a movie title. A book would be less likely to be directly associated with IMDb in this way. You can go to the IMDb page to confirm things like the release date, the actors involved, and the genre of the movie.
It might be a story about a parrot that learned to imitate the sound of a car alarm. Every time a neighbor parked their car nearby, the parrot would start making that noise. People in the neighborhood were looking everywhere for the 'car alarm' until they realized it was the parrot. It was really a comical situation.

Well, consider a dog. In its mind of a funny story, it was the king of the park. Every other animal had to bow down to it. One day, it strutted into the park with its head held high. When it saw a squirrel, it barked in a very regal way, as if ordering the squirrel to bring it a treat. The squirrel just chattered back and ran up a tree. The dog then sat under the tree, still imagining it was in charge, waiting for the squirrel to come back and serve it.
It could be special for its relatable characters. In a 'funny story novel', the characters are often what drive the humor. They might be ordinary people in extraordinary situations, and the 'kind of' aspect might suggest a certain quirkiness to their personalities.
There's no way to tell for sure just from that statement. It could be, if someone was writing about a book on Gradesaver and thought the whole experience of reading the book and using the site's resources was a funny story. But it also might not be a book review at all and could be about some other aspect of Gradesaver, like an interaction with the website's features or other users.
Sure. Once upon a time, there was a cat that thought it was a dog. It would bark at the mailman and try to fetch sticks. Everyone in the neighborhood was so confused but also amused.
