This is a bad analogy because there’s 100+ types of atoms. In anisogamous species (like humans), there’s exactly 2 gamete types, sperm and ova. Which of those two gamete types one’s body is organized around producing is how sex is defined.
See here for charts showing the spectrum of sex determination and how that relates to sex definition. Each chart can be labeled as male or female based on this definition of sex, which is the one that is used across the field of biology.
The information on the flow charts is directly from peer-reviewed developmental biology papers and textbooks on human sex differentiation.
But humans are a gonochoric species: individuals are either male or female throughout their entire life cycle. People with DSDs are not new sexes (this would require a third gamete type), and they are not both sexes (this would require the full development of both male and female gonads and genitalia in a single individual. A hermaphrodite has never existed in humans).
There’s no third sex, and there’s nobody born with a body that isn’t trying to produce gametes (and potentially failing).
