No. It's not outright stated, but there are organisations that have "A seat at the high table", it's implied that the Italians (formerly run by Santino D'antonio and his sister before him), Yakuza, Triads, Russians, and several others have representatives with seats at the high table.

There are then intricate lower-level factions that are associated with the high table but are not actually members, referred to as "under the table"; such as the Bowery King. Then there's your standard street level gangs that likely do business with the table or are recruited as foot soldiers for missions.
