It's really difficult to enjoy the game when you are losing because losing is like you failed. I understand some people do say that they gamble for fun which by extension mean that they enjoy the game even they are losing. Thus does not make sense in reality but since we have different mindset, it is still possible one can catch some fun even in the midst of losses. There was a time I was playing opposite of the bookies favourite, that is betting on the teams with the bigger odds. It was fun losing those bets because I knew for sure that the probability was against me.
