What does your 'Hello World' service do? Just print 'Hello World' to
the console and then exit?

If so that would be the reason why it is inactive. Systemd starts it
and then it exits. Typically, services keep running (except for some
special cases) once they are started. That's what makes them a service.
To stop them 'systemctl stop <service>' is used. By default systemctl
sends SIGTERM to tell the service to clean up and terminate itself.

To piggyback on that, it is possible to set Type=oneshot[1] for the
service so that systemd considers the service to be up after it exited.
I find it useful for init or migration scripts that another service can
then depend upon.
