Networks just suck, period. Imo, in WebRTC (which powers stuff like Zoom or Teams), there's nothing in particular that adds latency - connections can be peer-to-peer and it uses UDP under the hood, with latency optimized codecs, from that point, there's little left on the table, that can't be traced back to poor network quality.
