> But running a CDN at that scale is gonna require experience and truck load of money
Take Netflix for example. Their CDN at scale is pretty good for VOD type of delivery, but they continue to get it wrong for live event streaming. Even Twit..er, X falls down with their large event live streaming.
Adding the "live" component makes everything just that much harder
Live streaming with HLS is equal to distributing static files and can be very low latency.
If you need to go below 3s of latency, yes it becomes harder, but everything else is thankfully solved.
The bigger issue with live streaming are the peaks: 0 views in one second and millions in the next. Even with static content delivery that leads to all kinds of issues.

And truly live (which means probably under 10 seconds from lens to viewer - i.e. the time it takes for the "X win" notification to pop up on your phone) is even harder than traditional "live" in the 40-60 second window.
Ideally you want all viewer to view it at the same time (so when next-door are cheering on a feed 3 seconds ahead of you it's not spoilt).
