Is there a difference between relationship/friendship/family covert narcs and only FWB/sex/hookup covert narcs?…like how they think?

Long story short, tried hookup sites for the first time in my life three years ago. A covert narc and I got on the site at the same time. Told me I was their only meetup and secluded me at their house at night. Over three years I went through silent treatments, blocking, and one angry message where I was ignored for a month until begging for them back on the site (since I had a gut feeling they were messing around with more than just me but didn’t truly know at the time). Found out by snooping on the hookup site, they have sex literally every day with new strangers spanning different towns and all unprotected, and are thrill seekers. And though they are quieter with me, I guess they are very dominant, aggressive and verbal with others. I talked to more than 55 people and then stopped, who they have seen, and found out too much lol. Also talked to other regulars like myself, though I was the main supply who met with them the most over time until being cut down to once a month.

About two weeks ago stood up for myself and tried to gently ask questions and have a conversation, just to be yelled at and threatened to never come back to their house or they’d get the police involved or worse they said.

I’ve asked different aspects of this scenario on here before, but I never asked are sex covert narcs the same as every day covert narcs? Or is their unlimited supply going to keep them busy so I don’t have to worry about them reaching out to me and can stay on the hookup site I’m using? (I always had to reach out to meet my FWB, when apparently they reached out to everyone else but me the whole time). I only really used the site to meet with them.
