No, ORM is a particular approach to doing that; the query abstraction approach described upthread is closer to the DAO pattern, to which ORM is an alternative. People were using RDBMSs to provide a persistence layer for OO programs before ORM was a thing, but as you have broadened the term any use of an RDBMS to store/retrieve data used in an OO program would be "ORM".

Now you're the one using a nonstandard definition of ORM. Here is how Wikipedia defines it:

    Object-relational mapping (ORM, O/RM, and O/R mapping)
    in computer science is a programming technique for
    converting data between incompatible type systems
    in object-oriented programming languages.

"is a technique for" does not mean "includes every technique for".

Spearfishing is a technique for catching fish, but not every technique for catching fish is spearfishing.
