Based on the people I've talked to online I think people who get it before adolescence are certainly not the majority but are not a tiny minority either. You're far from alone in how you experience DP/DR.
Also I don't think depersonalization is actually that rare - it's just incredibly underdiagnosed and underresearched. Dissociation is something most people will experience at some point, and I would not be surprised if a couple % of people had DP/DR.
