950 is enough to find games in Pavlov for most gamemodes. SND, TDM, PUSH, TTT, Jailbreak and some custom gamemodes all have well populated servers right now and that's on a weeknight. 
You also have a bunch of smaller lobbies that could be playing anything.

It can sometimes be an issue when there's nothing between full and empty for the gamemode you want but it doesn't take long to nab a slot.
