Nothing is impossible when we are talking about sportsbetting. Over the last years I've seen crazy matches where underdogs win without anyone expecting such a thing to happen. I've seen it happen in tennis where the number 1 ranked player lost against 200 ranked player. I've also seen it happens multiple times in football where big teams like Bayern Munich lost against amateur teams from 3rd or lower tier. In such matches you can't even bet directly on the favorite to win because they are so big favorites the spoetsbook cannot offer them even 1,01 odds. So yeah, crazy bets are definitely worth a shot sometimes just make sure you don't place a lot of money on them since they happen extremely rarely
