In general, an association class is many-to-many if there are no numerical (cardinality) attributes on the association. If you want the association class to represent a many-to-one relationship, then the cardinality on the "one" side of the relationship should be marked with 1.
However, some developer conventions will not mark an association with cardinality when the cardinality is unknown. In these environments an unmarked association does not tell you anything about whether you have a many-to-many or many-to-one relationship. To indicate the many side of the relationship you should mark it with a cardinality implying "many", i.e. *, [0..n], [1..n], etc.
To answer the specific question: An association class is not always many-to-many.
