There are bad bets where people are certain they will win because the odds are bad and its not even worth betting at that point.  The reason being its always possible to lose, if everything has entered thinking they cannot lose the odds become easily a watch only event.   
  I much prefer the idea of value betting, small amount on a slim chance can be just as entertaining if not more.   It does depend if you like an underdog winning against all expectations, I personally like to see the unexpected so its not just money to me.  Dead certs are almost a classic meme as a mistake
