Well, all other things being equal (so ungroomed, nude, untutored etc) most people are averagely attractive, intelligent, talented etc. A relative few are ugly. A relative few are conventionally beautiful.
With resources, the average can become above average. Not exceptional, but certainly improved. Be that grooming, clothes, time, money, parental support, tutoring, enriching experiences etc etc.
It is economically advantageous (and deeply wrong) for women to appear thin, rich, white attractive and young. Thus smart women often strive to appear so. Smart women who are successful in appearing attractive (by male gaze standards) are more likely to be economically successful. And so it goes.
Also, many traits you describe are inherited or have a genetic component. Looks, well behaved hair of a particular colour, intelligence, charisma , money (and thus time and energy available to improve any of those things) on the positive side. Being overweight, neurodiversity, a harder time learning, Frizzy hair, time blindness etc etc. are also inherited to varying degrees.
More people seem attractive because many, many people strive to at least some extent to appear attractive. We are herd animals, biologically driven to fit in. Very, very few people are driven to appear unattractive. So a few go from ‘ugly’ to average. Lots go from average to attractive. A very few go from average to ‘ugly’. So the numbers are skewed heavily upwards. So it goes.
(when I use words like ugly, un/attractive and beautiful, I am using them in the sense of as defined by society. I do not believe they make people better or worse in any way personally)
