@Al Karaptian, Welcome to Microsoft Q&A,
Are .NET 6 and .NET 7 considered part of the .NET Core framework?
Yes, you are right. Before .NET 5, we often called it as .NET Core. And after .net core 3.1, it becomes .NET. However, they are the same thing actually, which is a cross-platform and open-source framework optimized for modern app needs and developer workflows.
You could refer to the following link to know the history of .NET and .NET Core.

Hope my explanation could help you.
Best Regards,
Jack
