They are not exactly the same, as many in this thread have already pointed out.
Yes, the basic condition, of being gender dysphoric and being 'women trapped in men's bodies' might be the same, but most of them lack the resources to physically transition, are forced to live in highly oppressive environments, have very limited economic opportunities, and their 'third gender' identity is more because they are ostracized by the 'mainstream' society as being outside the gender binary. Some may start to reclaim that label as a matter of pride, but it's not exactly the same kind of personal autonomy that non-binary people have in the developed world.
In contrast, the trans women who are not part of these communities, and who do not identify as 'third gender' but simply as women, are more like trans women in any other country in the world, developed or developing. It's a similar journey of medically transitioning and facing similar challenges as anywhere else.
