I know I'm sad but I had a look at the draw on the iPlayer and I think I see what you mean. On the Dream Number, there are seven numbers drawn each from 0-9 and they had wee numbers on. I also think I know why that is.
There are seven lots of balls, 0-9 that are whirling round and each of THOSE LOTS is numbered one to seven.
If you freeze the bit where they show the balls after the draw, youl'll see a wee "1" on the first ball a "5" on the fifth ball, a"6" on the sixth and a "7" on the seventh ball.
