You may need to expand on this point with some form of picture or flow-chart because I'm not seeing where you're going with this.

A Random Battle needs 24 players.
The matchmaker receives a player to match, sifts them into corresponding buckets and then looks for 23 other players. If the original player was in a Div, then the Matchmaker looks for another 22 or 21 other players.
The Matchmaker is only able to choose from the random string of players that are living, human beings and happen to click the Battle button in ships that fall within the Type and Tier (and potentially division requirements, but an imbalance of 1 div per side is allowed meaning a solo div could exist in a game with no opposite div) requirements. The smattering of people that hit the Battle button is random and uncoordinated (outside of clans or groups of people trying to sync-drop anyway) and so the Matchmaker grabs a random assortment of whatever shows up and fits the bill.
When there are enough players for a game or a queue dump, a game happens.

I'm not seeing the higher-order whatever that stops that from being Random. Further, I don't see why it would matter as the Matchmaker does not care if you win or lose, it simply gathers an assortment of players and puts them into a match.
