The underlying database for Dynamics 365 is Dataverse. Because Power Apps offers first class support for Dataverse, it provides a powerful way to extend the functionality and capability of Dynamics 365. However, there are certain tables that we cannot access without a full Dynamics 365 license and these are known as 'restricted tables'.
To answer this question, let's examine the licensing cost of Dynamics 365 Sales.
Dynamics 365 licensing works on a 'base and attach' model. To give an example, for a user that uses 'sales professional' only, the license cost is $65/month. If the user wants to access additional apps in the Dynamics 365 suite, the lower 'attach' price is chargeable for those additional licenses.
Let's compare this to the cost of the Power Apps per user and per app plans. A Power Apps per user licence (which provides access to Dataverse and unlimited custom apps) is $40/month. The per app licence (which provides access to Dataverse and up to 2 custom apps) is $10/month.
For certain use case scenarios, an organisation may choose to build custom Power Apps that integrate with the same tables that Dynamics 365 uses and in doing so, benefit from lower licensing costs.
To limit the scope of this practice and to help Microsoft protect their licensing revenues, certain Dataverse tables are restricted. With restricted tables, users with a Power Apps plan can read records from the table, but not create, update, or to delete records.

Where can I find out more about Dynamics 365 licensing?
The PDF licensing guide provides the most comprehensive and accurate information on Dynamics 365 licensing. The official Microsoft Dynamics 365 website tends to be more marketing focused, with less detail on the precise details of licensing.
The link beneath should always return the latest version.
One thing to note is that for use-case scenarios where users require limited, mainly read-only access to Dynamics 365 data, the team license and Team apps can provide a cost-effective solution, at around $8/user/month. There are more details here:
