Yes they would. Plenty of players, in fact the majority, have a sub-70% win whilst not playing setups that unrank the game via N1 action.
Games that go unranked D1 through course of action rather than veggies/suicides cause the game to go unranked and no points are given out, understandable. E.g https://epicmafia.com/game/3704048/review
Albeit losses are still given and recorded as loss on the most recent games list + on stats, personally don't think losses should be given to games that go unranked. Not sure whether this is intentionally programmed to be like this or if it's a bug but I'm creating this topic on the basis of being unsure about it. If it's the former case in which it is intentionally made to be like this then I think it should be changed.
