SharePoint 2016 comes with a good number of default User Groups to which you can assign different permissions for your Site. In addition to being able to create new Groups, you can edit the permissions assigned to Groups.
To your Site, a Group can have the ability to design, edit, contribute, read, view, or have full control. Using Groups, SharePoint allows you to assign permissions and access to several users at once instead of managing each user at a time.
In any case, as one of the best practices, it is advised that you do not change the default User Groups and their assigned permissions; instead, add users to different groups as needed.
To edit permissions for a User Group, just go Site Settings, click on Site Permissions to see the list of Groups and select that which you want to change.
The video below shows you how to change permissions for a User Group.
