Well,its not that radical like "every time a girl says that you are cute it means she sees you as a friend".
Sometimes yes, sometimes not, it depends on the context, as was said. She may think you are a handsome guy, but she does not necessarily have a sexual interest in you.
Watch out for other signs, does it touch your body? How close is she when she talks to you, what kind of subjects does she talk to you? Is her body language open and aimed at you?
Sometimes she can be an extrovert and was kind and nice to you, which is a common thing here in Brazil.
