yes those are different.
Clustering agent is something that overall look after the cluster (like who
are the members joined / left. Communication between the nodes)
Load balancer is a device / a software that will distribute the traffic
among the available nodes in a cluster

In a production set up you can have a Nginx load balance to distribute the
request among the clustered nodes.
By default WSO2 products uses Hazelcast community edition based clustering
implementation [1]

In other words. When you enable cluster in wso2 products Hazelcast
clustering agent is already available to take care of your cluster.
But a load balancer is optional,  if you don't want to distribute the
incoming request to the cluster.
