Their gender is, by definition, what they identify as. It's their birth sex that doesn't match. And the existence of intersex people proves not everyone is born as part of the binary, though they will often get treated as a boy or girl based on the parents' convenience.
Also, while it may be technically true that being non-binary would fit the definition of being trans for most people, not everyone in the non-binary community classifies themselves as trans, most likely because of the nuances among those communities. An agender person (who might not even consider themselves nonbinary) would have different thoughts, needs, and priorities from someone desiring a sex change, for example. Classifying gender identity is much more complicated than classifying meat.
What this all means is simple
Transgender is in the "LGBT+" rainbow, but the rainbow isn't transgender.
The fact there are people arguing that everyone who's sexual divergent from the binary is "Trams" is a gross oversimplification, and frankly the murmuring I've been hearing is the Gay/Lesbian, bi, inter, pan and nons all really want to distance themselves from Trans advocates since those people *Only* make it about themselves.
