As far as has been made public, all astronauts of any country have been trained on earth, began their space missions on earth, and returned to earth at the conclusion of their missions. Astronauts have died during launch or re-entry. None have been lost or died in space. So the answer to the question is: Yes, 100%, every known astronaut has been to earth.
In fact, if you want to round things off, every astronaut has spent approximately 100% of his life on the earth, and approximately zero in space.
