About the number of RIP hops

I recently encountered a question about the number of RIP hops and the maximum number of routers contained in a link. I am also confused. Is it 15 or 16? I checked it on the Internet and found that many people cannot understand it like me, so I had to check the information myself.

Huang Tianyan has no heart! Finally, we finally figured out that the maximum number of hops supported by RIP is 15. Because 15 or more hops are considered to be inaccessible, the maximum number of routers that a link of RIP can contain is also 15.

When data packets reach 16th vrouters, they are considered inaccessible.
