Nature comes pretty damn close to doing that, Octavia.
Given that you don't seem willing to put even the slightest bit of effort into sourcing what you post, I thought I'd do it for you.
So, according to the ever-reliable interwebs, 1 in 1,600 people have chromosomes other than XX or XY. Assuming that's correct (fingers crossed, since, ya know, it's the interwebs) you're looking at .625% (as in point six two five percent), meaning nature cranks out people with only either XX or XY at a rate of 99.375%.
So statistically, you're on pretty thin ice with that comment, imo, Octavia.
The one article I thought you *might* take the time to read is here, from the Mayo Clinic, regarding females with something other than XX. And yes, sorry to report to you that they say with scientific authority, that if a person doesn't have XX or XY, they suffer from a genetic disorder.

I'm sure there is much more material on this subject for YOU to research, so that for a change you can speak with some level of authority, should you decide to put the effort into doing so.
