Doesn't appear so. The main Minecraft Wiki states: "Occasionally, monuments contain a room with several wet sponges on the ceiling. Sometimes, these rooms can come in multitudes." Although I think Elder Guardians drop 1 sponge when they're killed, so I guess that yes it's 100% since that would mean you'd get 3 sponges (3 elder guardians) 100% of the time?
