It reminds me when I was younger, I truly did not have access to videogames since my computer did not have the required hardware to run most of the games which were being released back in the early 2010, but I still felt appealed by those titles and the story behind them. Because of it I started to watch streams and YouTubers to play through those games in an format of episodes. Eventually, many of those streamers I liked to watch for hours, moved to stream their gambling sessions, I was not a person who gambles much back in the day, but still felt like watching those people, since I grew up watching their reactions and adventures within the world of videogames.

He may have had a similar relation with Dana White, he does not necessarily need to be gambler to also enjoy the gambling sessions of others, as long as those do not prompt him to gamble recklessly, it should be fine for him (or anyone) to also keep in touch/follow gambler who also have other kinds of careers.
