Good question! A better plugin description might be:
Discourse Zoom empowers Discourse administrators and users with a paid Zoom subscription to schedule, manage, and participate in Zoom webinars directly from their Discourse platform.
(What do you think @Juan_David_Martínez and @pmusaraj? 
)
Both users and administrators can create webinars in Discourse. However, only those with a paid Zoom subscription for webinars can create them in Zoom. In essence, regardless of whether they are an admin or a regular user, anyone wishing to create a webinar must have a paid Zoom subscription. Currently, we don’t have the ability to restrict webinar creation by trust levels or groups.
One thing worth noting is that when a user creates a webinar, any administrator can edit, add panelists, or include the URL for the webinar recording. This is a privilege that a regular user cannot exercise for another user’s or an admin’s webinar.
We’re working to include this information in the topic itself.
