Can you clarify why you think that's the case?

pg_stat_statements certainly does need to be included in
shared_preload_libraries, or it will emit an error noting its not
loaded: ERROR: pg_stat_statements must be loaded via
"shared_preload_libraries"

The only exception to that is if you're in an environment where the
provider has already included it in the default configuration, e.g. on
Amazon RDS - but that is not the case with the regular Postgres
packages to my knowledge.

Thanks,
Lukas
