Custom Metadata : All custom metadata is exposed in the application cache, which allows access without repeated queries to the database. The metadata is then available for formula fields, validation rules, flows, Apex, and SOAP API. Custom Metadata Types stores the records in a memory cache which allows faster retrieval of data when you execute a query.
Custom Settings : All custom settings data is exposed in the application cache, which enables efficient access without the cost of repeated queries to the database. Formula fields, validation rules, flows, Apex, and SOAP API can then use this data. While custom settings data is included in sandbox copies, it is treated as data for the purposes of Apex test isolation. Apex tests must use SeeAllData=true to see existing custom settings data in the organization. As a best practice, create the required custom settings data in your test setup.
