If 99.9% fail and you see one that didn't, then would it be surprising that it didn't? No! It's not 100%, so there must be some example. For that one it's not surprising.

More precisely, it's not surprising that one exists. It may be surprising that this particular one survived, just as it wouldbe surprising that it's my neighbor who wins the lottery next week. But it's likely that somebody will, so if somebody has won, it won't be a surprise that somebody did.
