Supply and demand. There are women out there that cream over a 5ft 2 Indian janitor but the number of men that fit this criteria far outstrips the number of women that find this attractive, which is why those guys struggle. A small percentage of women want guys that are actually 7ft+ but the number of men that are that tall are so small that these guys won't struggle at all with getting laid.
Likewise, really big offseason bodybuilders are rare so even if a small percentage of the women out there find that attractive, they won't struggle dating as long as they're not crippled by something like a subpar face or height. Same with twinks, although some decent percentage of the young male population are skinny twinks but a large percentage of young women find that attractive so these twinks don't struggle.
You only struggle when your niche is relatively low in demand, you hit Chad status when your niche is relatively high in demand. This is why JBW works for passportbros and so does being black.
