Yes, it even says so in the man page
man 1 getent
The order in which entries are looked up
is defined by the specific database (for example, the lookup order for
the “hosts” database is determined by resolv.conf(5)).
I do understand where the confusion comes from though - it's the naming:
getent hosts database != /etc/hosts file
However, the same goes for:
getent passwd database != /etc/passwd file
as the former will also include YP accounts if configured.
Etc...
