Yes and No.

Many files on the system belong to the Admin user group to which your Admin user will belong. You can take action on those files/folders with the Admin account where you would otherwise not be able to with a run of the mill User account.

As an Admin user it is also possible for an authentication process to ask only for Admin credentials (instead of Root) to gain elevated privs. This means the Admin user doesn't even need to type their password. An Auth request will generally get elevated to Root when it is properly authorized by an Admin (who is obviously not Root themselves).
