That YouTube cooking video is probably ~10Mbit. Assuming the kids are watching 4K streaming video, its maybe up to 20Mbit per stream. So, you're at maybe 50Mbit of throughput with all your highest usage things going at once. Your phone being on the Wifi but not actively being used is practically no bandwidth usage. That podcast is anywhere from 320kbps to maybe even 64kbps, practically nothing compared to even one of those video streams which all together are only using half your bandwidth. Same goes with playing an online game, assuming you're not talking cloud rendered its maybe a few hundred Kbit. Rounding up all the other little things, you're looking at using maybe ~60Mbit down. 60% of your bandwidth.

It wouldn't take 100-gigabit to make this happen. You can already get this on existing VR headsets today. I watched some basketball games with a Windows Mixed Reality headset nearly a decade ago, and I definitely did not have terabit networking.
