The problem for things like video games and trading is that websockets only support TCP by default. Technologies like WebRTC allow for much faster updates.
I think websockets certainly have their uses. Mostly in systems where SSE isn't available quickly and easily, or when sending a bunch of quick communications one after another as there's no way to know if the browser will pipeline the requests automatically or if it'll set up a whole bunch of requests.
