So I know this particular guy named X; naturally I'm astonished to bump into him randomly on a specific flight from Y airport. But I know 200 people, and I take ten flights a year, there are about 200 travellers on each flight, and such random bumpings don't happen more than once a decade. It's rather unlikely that I won't randomly bump into someone I know, on some flight, sooner or later. But when it does happen, I'll still be surprised.
