A robots.txt verdict describes the published rule for the tested path. It does not prove crawling, indexing, training, citations or traffic.

Does this rule control every product from the same operator?

No. Operators can publish separate user-agent tokens for training, search and user-triggered retrieval. Configure each documented token intentionally.
