The info is correct, but to answer your question more specifically, may we know what exactly you're trying to find out?
The Xbox One X is great in that it is a backwards compatible console as well as a forward compatible console.
This means games in the Xbox eco system, games are not locked to specific console generations.
You can play a ton of Xbox 360 games on the Xbox One X and you can also play a handful of classic Xbox games (circa 2001) on the Xbox One X.
More games are being made backward compatible every month.
