what are the odds?

For me this is the first time using ticketmaster and because of personal reasons I can't attend a certain show in Dublin. What are the odds of these tickets actually getting resold? I suppose I am only going to get the money back if somebody actually decides to buy the certain tickets I put up for a resale? I AM NOT LOOKING TO SELL THE TICKETS IN THIS SUB I JUST WANT OTHER PEOPLE'S OPINIONS/EXPERIENCES WITH THE TICKETMASTER RESALE OPTION. Thank you all in advance.
