Well, not quite on the first paragraph. If the probability of losing each game was exactly 95%, the chances of going winless over 18 games is 39.7% (.95 to the 18th power). So, it's not quite that bad. It's more like the Gophers have a 16% chance of winning, on average, any of the remaining B1G games, though, which is still really bad.
According to t-rank, the game against Nebraska at the Barn on 1/7 is currently a 39% chance. That's currently the best odds of any remaining game.
Sorry for the stats class.
