Yeah, they are totally fine with gambling for sure. I was actually a bit surprised to see https://www.twitch.tv/directory/game/Slots near the top of "most watched games" when I was bored the other month and wanted to see what the popular games to watch were.
It's literally a bunch of whales flushing money down the drain on gambling while viewers watch it (vicarious thrills? not sure tbh as I'm not a gambler).
