Final answer:
An Azure service in private preview is not released to all Azure customers; it goes through phases including public preview before becoming generally available.
Step-by-step explanation:
The statement that an Azure service in private preview is released to all Azure customers is false. When a service is in private preview, it is only available to a limited group of customers for testing and feedback purposes. After the private preview, it might enter a public preview before it becomes generally available (GA) to all Azure customers. The transition from private preview to GA typically includes a public preview phase where the service is made available to a broader audience, but it is not yet supported for production use.
