Ugh, can we stop interpreting everything so literally? People embellish and use hyperbole for effect. Whenever someone says "always" or "never" (or similar terms), they very rarely actually mean those absolute terms, because most things in the world have exceptions, and most people actually do know that.

If you're genuinely confused by this kind of usage, and actually believe that those absolute terms are used sincerely, then I don't know what to tell you... maybe try to understand culture and language usage better?
