Can't reply to my sibling here, but no, they do not get their money back. Once a Kickstarter is funded, the money goes to the organizer and then it is gone. It's on their honor to deliver on their promises. Kickstarter does nothing to enforce that. It's somewhat by design, they don't want to saddle starving artists with tons of debt because they made a mistake on how much it would cost to fund the rewards. But that also assumes it's being used by starving artists. Kickstarter seems like it has largely become just an advertising and presales system for established artists and companies.
