Yes, but they are a small part of the server’s players and an ever smaller part of the overall PvP community. Those who do PvP here mostly do not frequent the forums, too. Posting this in the Arena forums would’ve been more beneficial to you!
This is correct as of BfA, however, pre-BFA PvP and PvE servers were seperated, meaning that the realms that had a high PvP population before BfA still have that population now even with the removal of specific server types.
I believe that Ravencrest and Sylvanas were both high-population PvP realms prior to BFA’s release, so I would reccomend those servers over Argent Dawn given how most roleplayers don’t PvP and vice-versa. They are two very different aspects of the game that don’t necessarily share an audience.
