Some of the pics on the above link have some village information on them. Is this information an addon or part of vanilla minecraft?
The wiki always refers to vanilla minecraft.
Assuming you're asking about the "No Village found" line in https://minecraft.gamepedia.com/File:Villagefig15.png (or the village center, door, and villager counts in later pics) those are not available in vanilla.
There are mods that would provide this information in 1.11, possibly in 1.12, I don't think yet in 1.13. [As I don't make use of these, I may not be up to date.]
The "carpet mod" will provide this (and a wealth of other infromation), but I don't have a link to a newer version (the above is for 1.11)
gnembon recently 'teased' a new project that ought to work in 1.13.2, but a release vesion does not yet appear to be available.
WARNING: I have an extemely "grindy" playstyle; YMMV — if this doesn't seem fun to you, mine what you can from it & bin the rest.
