The definition in my book says domain is all the x alues and range is all the y values.That is the most braindead definition I’ve ever heard. Did anybody really print a book containing such nonsense?

I think that the kid was misstating what he read. The domain does consist of x values and the range does consist of y values, just not necessarily all of them.
