Odds of Main Event winner being on Hendon DB?

[Whitewash]

What would you say are good odds to put on the winner of the WSOP main event winner being someone with a 6 digit tournament payout already recorded on the Hendon Mob database?

People always use the ultra-generic and hazy "will a pro or amateur win?" question, but I figure this is a much better and specific question to ask.
