Is there any difference between Mac OS X and macOS?

No, they are essentially the same thing just named differently. In fact, three terms were used at different times with reference to Apples operating system: Mac OS X, OS X, and macOS. Mac OS X was the official naming through version 10.7, from 2001 to 2011. In the next four years, the OS X names were used. Finally, Apple shifted to "macOS" with the release of macOS High Sierra in 2016. The latter helped standardize the naming of Apples operating systems macOS, iOS, tvOS, iPadOS, etc.
List of macOS versions

Brief backstory. In 1996, Apple purchased NeXT, the company Steve Jobs built after he had left Apple. The same year, Jobs returned to Apple and helped build the first Mac OS that could compete with Windows. Thats when it became obvious Apple could grow to become a big player.
The first ancestor of the macOS family was Mac OS X Public Beta released in 2000, followed by a public release of Mac OS X 10.0 in 2001. Lets recount the stories of all Mac OS X versions, up to the current macOS.

1. Mac OS X 10.0 (Cheetah)

March 24, 2001: Aqua interface is born with Mac OS X Cheetah. Its a big step in the evolution of graphical interfaces, with 2D and 3D graphics support, granting an all-new visual experience. Cheetah featured a water theme, which, according to Steve Jobs, "one wanted to lick when they saw it." Beauty comes at a cost, though. Graphics improvements made Cheetah very slow, which prompted Apple to shift focus from visual experience to performance in the next release.

2. Mac OS X 10.1 (Puma)

September 25, 2001: As you might have noticed, the first generation of Apples operating systems was named after animals. Puma arrived with a solid performance boost and a few other functional improvements such as simplified CD and DVD burning, new features in Finder, and more extensive printer support.

3. Mac OS X 10.2 (Jaguar)

August 23, 2002: The third release of Mac OS X added search to Finder (can you imagine it, Finder used to exist without it!) Jaguar also brings MPEG-4 support for QuickTime, a range of privacy features, and, for the first time, Accessibility API called Universal Access. Some of the apps born with this release continue living on Mac even today (for example, Address Book, which is now called Contacts).

4. Mac OS X 10.3 (Panther)

6. Mac OS X 10.5 (Leopard)

7. Mac OS X 10.6 (Snow Leopard)

August 28, 2009: Leopards successor, Snow Leopard, focused on expanding 64-bit architecture. Most of the native applications were rewritten in 64-bit.

8. Mac OS X 10.7 (Lion)

July 20, 2011: With Lion, Apple brings lots of useful enhancements from iOS to Mac OS. Launchpad, multi-touch gestures, and more. Interestingly, many people criticized Mac OS X 10.7 for the so-called "natural scrolling," which moved the content up when you scroll down. Back then, it seemed more natural to have the content move down as Windows did it.

18. macOS 12 (Monterey)
