How can a tiny USB-C cable power my computer then display 2 monitors and a TV. It also has a keyboard and mouse and a camera. The USB-C is connected to a port then the port goes to all of the other devices. I know the port connects to the device but the computer still has to send data through that cable to all the other devices. It seems that everything would bottleneck through that cable. Thank you in advance to all those who post.

All the devices end up bottlenecking into that one cable, but it’s moving too fast to make a difference. with enough devices you’ll reach a slowdown.
USB 2.0 had a max transfer rate of about 35 MB/s, about ten MP3 files per second. 3.0 went to 300 MB/s , or 85 songs, and 3.1 gen 2 or USB-C is 1.2 GB/s, or 342 songs, about ten times the speed over a decade ago. That’s enough to control several devices running full speed at the same time.
Power is different and separate, the hub is usually designed to provide power when the amount dedicated to the cable isn’t enough.
A hub with no power supply would be limited to the power output from the primary device it is plugged into, though that can be as high as 100 watts.
