These are not real friends these are Facebook followers

No, it's simply a network thing. People who have a lot of friends are more likely to be friends with you, and people who have few friends are less likely to be friends with you. The result is that if you have an average number of friends, your friends will on average have more friends than you do.

I do wonder what percentage do you have to be in to have friends that have the same number of friends as you.
