As windows server 2019 introduces some groundbreaking features that aren’t included in 2016 version, and microsoft does not intend to provide these features or any other new features to windows server 2016 from this point onwards.
The main difference is in the features of both, as 2019 is a newer version it comes with new features that you cannot get on 2016 but also 2016 version has some features that are now deprecated in Windows server 2019. The main reason for deprecating any features is because a new feature fills in its spot or some code level optimization leaves that old feature useless hence removed.
