I wish stuttering terminology was different from normal disfluencies of non stutterers

I wish stuttering terminology was different from normal disfluencies of non stutterers The word "stutter" refers to the actual condition, but it looks refers to fluent people who mix up their words when they are nervous. The word "disfluent" also refers to fluent people who use a lot of "likes" or "ums" when talking. I just wish there was different terms for the actual condition and normal disfluencies that non stutterers have. I had a professor today who literally said "people enjoy talking to people more when they speak fluently" I know she was referring to people who use like and um a lot, and not actual stutterers, but it still hurt to hear her say that.
