Hi ,
Primary Key: Used within data extension as a unique identifier WITHIN THE DATA EXTENSION. Data extension as used to store data within marketing cloud (regardless of which application), and enforce Relationship Database rules, like any traditional SQL based database.
Subscriber Key: An Email Studio attribute that is used as a unique identifier for contacts records. Has a one to one relationship with subcribers and is immutable (cannot be changed once set). This is a user defined property
