Lucky Number

I read "Lucky Number". Charlie does not go to school and works for a living for his family all day. His work is to shine shoes at Cafe Colombo. One day, he picks a lottery ticket up. His family is poor, so they wish for lucky number. Next day, it declares for the lottery. A man shouts out the winning number.
But, this book doesn't appear the last number. I am concerned about their lucky number.
