A drag queen is an entertainer and drag is an art form. Some are cis men, some are trans women, some are trans men, some are non-binary people and some are cis women. The vast majority are queer, but some are straight people do drag too. So basically anyone can do drag, but the majority are queer cis men.
Also transvestite is an archaic term and is mostly offensive/derogatory.
Serious question: is transvestite derogatory in its use in The Rocky Horror Picture Show?
No, not at the time it was made, but the modern LGBTQIA+ lexicon has moved on from it
Edit: I should have also said the "She-mail" thing was heavily criticized by former contestants as well, which was probably an additional factor that made the show change the name

Fun fact: On Drag Race, Ru used to give messages to the contestants and called it "She-mail", but they (reluctantly) stopped calling it that due to heavy viewer criticism
