It looks like it is possible for the /locate to find a location where no ruined portal is. It happened to me.
How to reproduce:
Genereate a new world with this seed: 4771793737520915822
Run this command: /locate Ruined_Portal
Teleport to the coordinates (The command is: /tp @s -320 ~ 192)
What I observed: You won’t find a ruined portal.
What I expected: I would find a ruined portal there
Update: It seems like it is inaccurate.

Good job finding it, remember to look for it in spectator mode, so you can see X-Ray in case it's underground
I was only searching underground and the ruined portal is at the surface. It seems like the locate command is inaccurate. The ruined portal was not exactly at the same position that the command said.
I don't believe this is resolved.... see : https://bugs.mojang.com/browse/MC-178842
I found the ruined portal.
