What happens if NOBODY else enters a guaranteed tournament?

So I have seen a couple poker tournaments with (3 seats guaranteed) and two players entered.

Also I have seen a tournament with 1 player registered and concluded that was guaranteed 20k.

So does the player win the ticket/or the satellite ticket if nobody else registers? or do they get a refund. Or do they get a refund and any kind of bonus?

anyone with insight on this please respond! thanks!

Also I have seen a $500 guaranteed finish with only 1 entrance. did they get $500? or did they just get a refund?

Here you can see the Tournament cancelation Policy.

The tournament wont start without a certain number of minimum players. If you’re registered you’ll just get refunded your buy in.
