Lotto processes work the same in any situation you apply them to, even a draft lottery. It can be as simple as a raffle at your work place to deciding who qualifies for gas in their vehicles after a natural disaster. That is just the way it is designed to service. Not much different from flipping a coin to see if it lands on heads or tails. The lotto process pretty much gives everyone an equal shot at the same opportunity. No discrimination, just classic way to decide on something.
For pick 3 and pick 4 games, this would be to pick a winner but in this situation, it is much different (what you are choosing). The stakes of the outcomes are much more risky. Draft lottery processes were created around the early 1970's. This is.
