As with most components on a Linux system, the systemctl command has a man page.

In this man page, you'll find a table titled is-enabled output where you can learn more about the different terminology printed with your status commands.

We have one service of the indirect state, which the table lists as having the following meaning:

"The unit file itself is not enabled, but it has a non-empty Also= setting in the [Install] unit file section, listing other unit files that might be enabled, or it has an alias under a different name through a symlink that is not specified in Also=. For template unit file, an instance different than the one specified in DefaultInstance= is enabled."
