Do most models not act stuck-up at all?

I use to think that models would act stuck-up and snooty because of what people have told me and TV is definitely an influence. But recently I met a model on youtube (not giving out her name for privacy reasons.) and she does not act stuck-up or snooty or anything like that at all, in fact she is one of the NICEST people I have ever got to know on the internet. This makes me wonder if I was drinking BS juice and that models in general do not act stuck-up. Does anyone know if most models are like this or not? I would really like to know because it would completely change my look on things.
