Hey Brryce,
If users are admin users, and have access to your WordPress admin area and they can publish normal blog posts too, then yes, they can create events in the admin just like creating posts.
If, however, you mean if un-logged-in users can submit events from the front-end, this is not possible without our Community Events add-on. You can learn more about this add-on here → https://theeventscalendar.com/product/wordpress-community-events/
Let me know if this helps!
Thanks,
George
