If you have a dice that has numbers 1-10 it does not mean that in ten rolls of that dice 1 rolls. Every time you roll the dice, you have a 1/10 chance in getting 1. If you don't get it, that changes nothing. Next time you will still have a 1/10 chance getting 1. So it is possible to never get 1, and that means that the reward system is balanced. [spoiler]this is very basic stuff, but op seems confused about random etc.[/spoiler]
