What do we mean by saying: Narcissist are not empathetic?
The people you know may have narcissictic personality traits, but that doesn't mean that they meet all the criteria. Criteria lists can be very confusing. Most of the time, people who are diagnosed with mental illnesses don't meet all the clinical criteria, even if their pathology is quite severe. 

I don't think the statements you give are necessarily narcissitic. A statement that describes the style of lack of empathy of a narcissicist might be something like, "I don't care if you want to eat pasta, because I want to eat sushi and what I want is more important." This is how psychology usually describes lack of empathy: a pathological inability to recognize that other people's feelings are equally as valid as one's own. 

At any rate, lack of empathy is only one of several features of narcissicistic personality.
