Does having single broker in Kafka mean when one consumer is consuming others have to wait ?

In Kafka, one can have more broker and that can form a Kafka cluster.Does having single broker for Kafka mean when one consumer is consuming others have to wait ? Thanks

One broker can have one topic. Multiple consumers can consume the same topic at the same time.
One topic can have multiple partitions. So, for example, if we have 3 partitions and 2 consumers. Consumer 1 can read partition 0 and 1. Consumer 2 can read partition 2.
Both consumers can read the different partitions of the same topic at the same time.

Thanks. So, understood that multiple consumers can consume from different partitions of the same topic as partitions is what parallelism depends on.
