Answer
A ServiceAccount provides identity for Pods to authenticate to the API server.
Quick Answer
A ServiceAccount is an identity for Pods — it determines what API permissions the Pod has. By default, every Pod gets the default ServiceAccount with a mounted token. Assign a specific ServiceAccount with narrowly-scoped RBAC roles to Pods that need to interact with the Kubernetes API (like operators and controllers).
