Yes, there are terrible females obviously (unfortunately more terrible than those worth the time of day)... however, I am directing my reply to males.
It's not all looks, not even the majority. As long as you are presentable with your appearance, stay in decent shape...but combine that with mentality, personality, financially (don't have to be rich, but successful in your own area and pushing for more) and many other traits.... You will win even in your mid 20s. With the curve increasing with age.
You can even compete with and defeat the "hottest" of guys at that point. Guys who only check one box of "being sexy" are used for temp rebounds and drunk tomfoolery, but thrown away for quality men ( or kept by dumbass women who attempt fix up a lime, a quality make would not want them anyways)....
Though even shit males who push only on looks are defeated easily by males with the total package, especially as the age increases. Not to mention, the one trick pony "hot males" are typically fat and losing their only asset in the 30s anyways.
Not different than the hot cheerleader who is 60 pounds over weight with 4 children and no future in their 30s
