I bought one of those USB-C to HDMI adapters just to find out that the USB-C ports of my desktop computer, my laptop and my phone do not support HDMI over USB-C.

Some devices only have DisplayPort alternate mode output, so may need a cable (or adapter) that does the DP->HDMI conversion. Assuming your devices support DP Alt. mode. These are active adapters.

USB-C to HDMI adapters are not the same as display link.

DisplayLink is a janky proprietary virtual framebuffer thing that is pretty similar to the linked project.
