For trans women, the terms exclusively refer to vaginoplasty. Non-op = those who are not planning to ever have it done, pre-op = those who are planning to have it done, post-op = those who have had it done. So, yes, a trans woman who's had an orchie, facial surgery, boob job, hormones, fully transitioned and full time, but does not want vaginoplasty is non-op.
Trans guys don't have the same obnoxious hierarchy related to bottom surgery, so I don't think the terms matter so much for you.
