What does this mean in practicality as a user? Will e.g. video calls be closer to real-time? There's usually about 0.5-1 second delay which leads to a lot of hiccups and interruptions when speaking with each other. What other application uses will be significantly improved?

This only resolves one source of delay in one ISP's network. Internet video chat is a mess because it's "best effort" at every level.

The need for <3 Mbps bitrates means tough trade offs between quality, bitrate, CPU time, and latency. Bitrate is the hardest constraint. Commodity laptops have slower CPUs or if they have 6 core CPUs they keep them clocked down when on battery. Hardware accelerated video encoding is not universal. So quality and latency are sacrificed.

Wi-Fi adds latency, especially when a laptop is on battery

To deal with NAT many video chat services relay through cloud servers adding latency.

It makes new cloud-based apps realistically & reliably workable - think cloud gaming and cloud AR. It also makes interactive stuff like gaming and video conferencing perform a lot better w/o lag. But really anything interactive (user & device) should be better given how many round trips it currently takes to paint a web page or stream video to handle an AI assistant (Alexa) interaction.
