Do you find that people who claim to be "unique" are mostly all the same?

It seems to me that a lot of the people who think they’re “unique,” “different,” or “individuals” who do things to prove it are pretty much all doing the same things to prove it. People who say things like “I’m a very unique individual, I’m sure you’ve never met anyone like me.” Either dying hair, being “artistic,” getting tattoos, etc. to prove how “unique” they are. Or embracing a controversial religious or political viewpoint (even if they don’t understand it) just for the hell of it. Is this just me or has anyone else noticed this? I’m sure the oh-so-unique haven’t.
