This is only partly true.
Of course, highly marginalized groups with extreme preferences exist. But you will not be able to appeal to 90% of the population
.
Symmetry in facial and bodily features, along with a moderately athletic physique, tend to be universally favored traits.
Then, there are some dimorphic traits that are attractive only to males or to females. For men, this is generally "square" appearance, and for women, this is "being curvy" (not only the body but also the face).
The exact preferences can vary slightly between cultures, but they will generally be consistent with the above.
I have seen studies on the above but I am too lazy to link them
. You can search for "attractiveness", "beauty," etc., on PubMed and see it for yourself.
Personally, I think there are some thresholds for being beautiful in your environment (like culture, social media, college, etc.). The only problem is that if you are below the lower threshold (i.e., ugly), you will most likely be excluded, but if you are above the higher threshold (literal goddess/god), your returns will be marginal at best.
However, I also think that sometimes people are conditioned to think in a certain way about a particular appearance. Specific traits become associated with certain groups, leading individuals to automatically associate similar traits in others with the qualities/status of the associated group. For example, hollow cheeks in Hollywood. This is attractive when men have it, but not women (I mean, literally hollow cheeks, not the "low body weight" cheeks).

To the OP
@LevUwU, I don't know how old you are, but if you are young, you can actually change (It can take some time, but there is a chance). I used to wear an oversized hoodie, a mask, and a cap literally every day to college
; those were the rough days...
You can have some underlying condition (e.g., related to your hormones). I knew some people who suffered from PCOS, and they resolved it once they got help from a
good doctor.
Frizzy hair can be fixed by finding a working combination of a shampoo and a conditioner (it took me around three years).
Skin and face shape can also change significantly with makeup. You can also influence your "wrongful" face somehow with the correct haircut or accessories like glasses.
So I would say while you might be in a terrible spot now, you can try to get out of it if you have some hope left.
