SSO (Single Sign-On) simply an authentication method that allows you to access multiple systems with a single ID/authentication.
Seamless SSO is a functionality of Azure Active Directory Connect, that allows you to authenticate seamlessly to the AAD (and any systems connected to AAD), without having to manually enter your ID/password. So, an SSO authentication that requires less user input.

Good question and as usual, MS don't provide good enough explanations on their solutions.
Azure Active Directory Seamless Single Sign-On (Azure AD Seamless SSO) automatically signs users in
when they are on their corporate devices connected to your corporate network

Important: Seamless SSO needs the user's device to be domain-joined only, but it is not used on Azure
AD Joined or Hybrid Azure AD joined devices. SSO on Azure AD joined, Hybrid Azure AD joined, and
Azure AD registered devices works based on the primary refresh token
