Characters and People in Vegas Poker Rooms?

I haven't been to vegas since 2012. Back when i was there, i played mostly low stakes at wynn and caesars for a few months before i left. Even though i played low stakes, i recall the floor ppl remember me and know my name because i played there a lot. Im curious but would it be safe to assume lot of the floorpeople and dealers and players there back then probably aren't there anymore?

Also i assume its fine to ask about certain ppl whether they are floorman or dealers etc if i just give them a description and not their name? Almost all, ii don't remember their name as its been a while. This was around Fall of 2012 or so.

Wynn- I recalled back when i went to the wynn, there was almost always 2 people who were there at the podium where you sign up to be put on list.

One was a pretty young guy, i guess late early 30s who was pretty tall. He sort of looked like that young guy from the Office except he had dark hair.

Also there was a lady that worked at the podium as well... middle age and brunette and very friendly i recalled. She sometimes even played 1/3nl at the wynn. I don't have a clue or remember their names anymore. I assume she no longer works there anymore?

There was this Asian guy i recalled who i kept hearing people call Jacky. This guy always seem to play 5/10nl or whatever is the highest game and i heard ppl say his name a lot at the poker room. I assume this guy no longer plays there? Was he some high stakes high roller or something? I recall he would buy in very deep at 5/10.

Cowboy Guy with Dice- This guy i seen a lot play at the wynn back then when i was there. He had a cowboy jacket, hat... also cowboy boots as well. But he had dice that he rolled... he would say things like okay if i roll a certain number, i call or fold. Of course i knew this was like an act. But is that guy still there?
