Pretty people absolutely exist. What you're noticing is that much of our awareness of pretty people through people who are fulfilling a social function by looking pretty, and these people have their attractiveness exaggerated in order to facilitate that work, which in turn creates a warped notion of what "pretty" looks like among people who don't habitually surround themselves by unhacked beauty as part of their lifestyle (e.g. models and performers who see one another when they're not done up). You see the same sort of pattern with other virtues that are "celebritized" and made symbolic, like "genius" and "creativity". But pretty people absolutely do exist, and even if they don't naturally look like what you see on a movie screen, they do have a lot of the benefits (and drawbacks) of being pretty even before they put their kit on.
