say your application has 120 tables. Do you write out 120 "INSERT" statements, 120 "UPDATE" statements, 120 "DELETE" statements as raw strings or otherwise every time you need to do any DML ? if not, and instead you have something that dynamically writes these out given some kind of object state to persist, you are using an ORM.

similarly, when you transfer the states of structures and/or objects to those INSERT/UPDATE/DELETE statements, or the rows from the cursor execution of a SELECT statement into object/structural state, that is also using an ORM.

I tend to consider "a query builder that writes SELECT statements" to be the least important thing an "ORM" can do, and is not even necessary to still have a library defined as an ORM. The "mapping" is mostly to do with automating the movement of data between the objects / database, which is, the relational tuples mapped to object attributes.
