Maybe parts of it. In that it's extremely unlikely in ten years you'll talk to more than one person from your high school, but you'll still talk to many of your friends from college.
The problem with high school is you are stuck socializing with the people who happen to be geographically close to you. You don't get to choose who they are, so they could be a bunch of jerks and you can't do much about it. At college, that is WAY less likely to happen.
But you still can learn interesting stuff in high school, AND socially it's still an important step to go through all that dating/hanging out/partying stuff. You could wait until college to do that, but it would be awkward.
