From what I've seen, a lot of time. These people aren't just discussing anything about games or what not, they're actively researching stories no one else has covered online yet. For example, the Boundary Break channel is all about reverse engineering games to disable camera restrictions and take them outside the game world. That takes a lot of time to set up, especially as each game needs to be treated as its own thing due to how they're coded. Probably dozens of hours with the community on Discord figuring how the camera format works, then even more using it to explore the hell out of the game to find interesting stuff before even making the video. Or in the case of Slopes Game Room/Guru Larry/Top Hat Gaming Man, looking into game series and games either from decades past (which have very little documentation online) or aspects of games people didn't know about. It's only thanks to them that stuff like Drivergate (a scandal where a video game magazine publisher gave artificially inflated reviews to a broken game to get the reviews out early) came to the surface or got added to Wikipedia in the first place. A lot of time goes into these videos, it's just a lot more of it likely goes to research and journalism than editing.
