So you are both correct. 4K60p output is possible with 4x chroma compression, but in general you would not want a computer monitor connected this way though it would be fine for a 4K TV.
As FYI TB3 peak theoretical rate is 40 Gbps. TB3 is included in the USB 4.0 spec.

Limitation due to bandwidth.
And how is this adapter [amazon.com] able to support 60Hz 4K over the same connection?
Refer to some discussion on second page

And that product costs more than this so it seems like the more expensive unit supports Thunderbolt 3 specs. If your computer doesn't have TB3 then you won't get 4K @ 60.

USB 3.2 bandwidth can't support 4K @ 60 and support all those other connections at USB 3 speed at the same time. They could be claiming 60 Hz when other connections are using usb 2 speed. You believe what you want cause this is just waste of my time.

Some USB-C hubs specifically mention that they require support for Alternate Mode, but some don't. Doesn't mean that's not how they work.
