If the timing and circumstances are right, anyone can be caught out by a scam. You can fool all of the people some of the time, which means we are all potential victims, though that doesn't mean you will necessarily be caught by a scam one day. It just means that nobody is so special that they are immune to it.

PS - I have been fooled once or twice.
PPS - Though the definition of "scam" is probably stretched in those cases.
