The point of lottery games is to offer the lowest possible probability of winning that has a perception of being winnable.
So guessing few random small numbers feels easier than picking one random large number.
The whole point of the website is to show those games in a context where people without a math degree will get how low the winning chances are.
So the games with the same winning likelihood Are Not the same game.

If the prize pot was say £10m, 4 winners would get £2.5m each.
I suspect that the hunebr of people choosing 123456 would be far higher than choosing 6 random numbers. Thus in the event your numbers did come up, you would get far less winning than someone who had the same odds but chose say 13 22 32 35 40 42
