It's Not Personal: A quick history of the geodatabase and why personal geodatabases are not in ArcGIS Pro (esri.com)
It’s Not Personal, is the first blog in this blog series and explains why personal geodatabases aren’t supported in ArcGIS Pro.
Microsoft has deprecated support for the Microsoft Jet Database Engine 4.0 libraries and considers the Data Access Objects (DAO) technology obsolete. This is the Microsoft technology that previously made support for personal geodatabases possible in ArcMap within ArcGIS Desktop. Also, there are no 64-bit versions of these libraries and ArcGIS Pro is a 64-bit application. Since the technology used to make personal geodatabases is no longer supported and Microsoft is advising against using these deprecated formats, there is no viable or supported path forward for offering personal geodatabases in ArcGIS Pro. Moving forward, our recommendation is to migrate your data from a personal geodatabase to either a file or mobile geodatabase.
