No, a trans person is a person with a body that is one gender, but who identifies as the other gender (assuming binary genders, which is an issue the broader trans community would probably dispute with some vehemence).
Some trans people only think it, some take supplementary sex hormones (typically testosterone for FTM; and one or more of the female hormones, and possibly also anti-androgens for MTF), and some have surgery to give them parts that match their identities.
You're thinking of cross-dressers, which community has some overlap with the trans world, but is, in general, a different thing. Cross-dressing is generally also a kink, while being trans is an issue of identity.
