Replica can exist in single node setup?

Elastic Stack Elasticsearch

If I have a single node setup and for each index say I have mentioned 2 shards and 1 replica in index settings. As it’s a single node there wouldn’t be any replica right? Only primary shards.
Please tell me if my understanding is correct.
