For context here: I made the video and am the lead video editor for RGL so I have a shocking amount of thoughts for a shit post that took about 15 minutes to make on my lunch break.

And you're right. Casual players don't use callouts. Similarly, I don't play CS and yet I watch a lot of counter strike videos for some reason. Never even casts of the match but a lot of like smoke line up videos and all of 3kliks and so on. Same thing with smash and some of those YouTubers. You don't need advanced knowledge to find the details of a community interesting.

To add to that, you don't really need to know the normal callouts (or even play tf2) to understand that 9 objects all named "house" is a bit ridiculous when placed back to back. Add to that the confusion based around why a bridge would be called "Japan" and most people's first ever viewing of Dogbread and you have a final product that ultimately went viral for a reason. It's funny to everyone, comp and otherwise, for a different reason.

To a competitive player, pub spot is a completely normal callout. A casual player will just be like "yeah that's the pub spot" (confirmed by someone commenting that they agree with that callout despite never playing comp). Similarly, shit house. Not inherently funny on its own but it is funny with the contrast of being put immediately after the word House 9 times in a row.

I do my best to make videos ABOUT competitive without making them exclusively FOR competitive players. I'm definitely not perfect yet but hey I also expected this video to bomb and it's quickly becoming the channel's most popular video ever despite me also originally thinking it would get 200 views and never watched again so clearly in that respect I have no idea what I'm talking about.

All in all, I hope you enjoyed the video at the very least and sorry for the long essay.
