There's no such operating system as plain 'Windows 10'. The two editions which are offered to home users are 'Windows 10 Home' and 'Windows 10 Pro'. (There's also 'Windows 10 S', aimed at students and teachers, and 'Windows 10 Enterprise', for IT-based organisations).
If you see a computer offered with just 'Windows 10' it almost certainly means 'Windows 10 Home', so there's no real difference in the terms.
While the 'Pro' editions of earlier versions of Windows possibly offered a few features which might have been useful to the average home user, Windows 10 Pro doesn't offer any such features. (It's mainly concerned with things for business users, such as allowing remote access between computers).
So 'Window 10 Home' (which might be advertised as just 'Windows 10' anyway) is all that you need.
