I always thought distributed systems weren’t necessarily decentralized systems. Is my understanding of the terminology wrong?

For example a system that uses distributed algorithms for performance improvements, or a system that is distributed by design and necessity to retain the benefits of redundancy, could be considered both centralized and distributed.

Nope. Your understanding is spot on. Mine is the one that's flawed :P.
