Statisticians are working less with managers than developers. Developers are supposed to be constantly fed back from the product users, and in practice, it means they interact with a bigger surface than statisticians. They may find ways to avoid interactions, but it is not "because developer is not people-related", it's because they want themselves to not be people-related. So, no, computer science is not less people-oriented than statistics. You may personally interact less with people, but it is just because you are personally less people-oriented, not because your job is fundamentally less people-oriented.
