What does client/Server owned Actor means?

if you look at RPCs | Unreal Engine Documentation

it talks about server owned and client owned actors, what is it ? is it same as owner passed in the spawn parameters?

does a server owned actor means the one that got owner which has Role_Authority on server?

I reckon this question is nearing 2 years of age. Yet for completion’s sake, if I gather the information from this question correctly, anything spawned on the server outside of a PlayerController is considered Server owned. Everything spawned inside of a PlayerController (also on server side) is considered player owned. I’m only left to assume parts of persistent maps are unowned actors.
