I know it may seem contradictory, but according to this Help Article, this option is no longer available:
"The option to subscribe to the entire Coursera catalog is no longer available. If you had a catalog subscription and it has been cancelled for any reason, you will not be able to re-subscribe to the catalog."
One may conclude it's available for a group of learners based on what you shared. Perhaps it talks about those who had access to it prior to its removal? Personally, I've not seen this option. To clear up your doubts, it's better to contact the support team using this link.
