Boron, please note the perhaps-too-subtle distinction I made: "won" as defined as "cannot be stopped". There are still many turns to go after such a point before all other players have either been crushed or they've given up. In SP games on Orania I reach that point in the 40s (as the AI is a much weaker adversary), and sometimes as early as the 30s. Just because the map has almost 300 provinces doesn't mean I have to conquer even half of them before I'm certain of a victory. Sometimes all it takes is 10-15% of them. The rest is inevitable.
