I am still trying to fully understand this because are love and gambling not life?
If I am lucky in love and in gambling, it should mean, too, that I am lucky in life.
It could mean that but not necessarily. You might win a jackpot the same week you married the love of your life. You just got that big promotion and a significant pay increase. Everyone is happy and life seems great. At the same time, you might be suffering from a serious health condition you don't even know about and only have a year left to live or someone close to you dies and your life gets turned upside down. That's not exactly lucky.
