"Please tell us about this imaginary lottery where a winner isn't even possible."
If a lottery is run like a raffle where only the terminals pick which numbers are sold and have a drawing that picks a winning number that wasn't sold then you have a lottery that a winner isn't possible.
Lotteries with self picks also draw winning numbers that aren't sold but it was possible for someone to have picked that number.
I don't think many people would buy tickets for a lottery ran that way, I know I wouldn't.
You're confused about how it works.
The drawing can result in any of the possible combinations being selected, and that combination may or may not match a combination that was played. As long as at least one combination has been played it's possible that the combination that is drawn will match it, and there will be a winner. Unless every possible combination is played (which has never happened in a jackpot game with many millions of possible combinations) a winner is never guaranteed. In most drawings for jackpot games there is no winner, but a winner is always possible.
How the combinations people play are chosen is completely irrelevant to whether or not a winner is possible.All that matters is that combinations are played and a combination is drawn.
How the combinations are chosen will have a minor effect on how likely a winner is. When people choose their own numbers they tend to favor a subset of the numbers in the matrix, so for a given number of tickets sold fewer combinations are used. Randomly generated combinations don't favor a limited subset, so more combinations are used for a given number of tickets sold. That means that rather than making it impossible to win limiting tickets to QP's would make a winner somewhat more likely.
