[Phantom Menace] are Sidious, Maul, and Dooku the only sith alive in the galaxy?

If not, then where is everyone else?

Plageuis and Palpatine weren't exactly public with their Sithiness. There very well could have been 2(or more) other Sith elsewhere, keeping it equally secret. No way to know. Sith don't go building giant temples in the middle of the capital city or taking people's kids in the thousands to indoctrinate into their religion.
