The application needs a data manager to manage its data. The data manager is a convenient place to put the persistence feature, if it is needed.
Persistence is not a necessary feature for a dbms.
If a system provides only persistence, it is not a dbms.
Thus, persistence is neither necessary nor sufficient to define a dbms.
If one thinks that what a dbms does is provide persistence, one has not yet begun to understand the role of a dbms.
