Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support.
According to the below site, I believe windows 10 Pro version 1909 is End of servicing and Windows 10 Enterprise version 1909 is supported.

Are the 1909 security updates released now specifically for supported Editions such as Enterpirse?
Also, can the 1909 security updates released now be applied to Windows 10 Pro?
When it is out of supported, then you won't receive any new update and in case update is supported like for Enterprise edition, then in some case you might deploy them manually but it might not work and sometimes you see error like not applicable and this is not a supported scenario.
It is recommended to upgrade to the supported build (which is free) to make sure you receive latest update.
Hi TN-3220,
According to the articles linked below, Win10 1909 Enterprise is supported until May 10, 2022. The Windows 10 Pro 1909 version went out of support on May 11, 2021.

According to these articles, once the editions reach the end of their support no updates will be released. Therefore, it's not possible to apply Enterprise updates to the Pro version.
You will need to update these Win10 machines to later versions.
