In WordPress, the distinction between an "Admin" and a "Super Admin" primarily applies within WordPress Multisite, a feature for managing multiple websites from a single installation.
An "Admin" oversees an individual site, with control over content, users, and plugins limited to that site.
Conversely, a "Super Admin" acts as the network administrator, overseeing the entire Multisite network. They can configure network-wide settings, manage users across all sites, create new network sites, and assign roles network-wide.
