Three 3 in 1 cable carries 3 signals: hid interface for the drawing capability, power, and hdmi signal.
I have seen some tablets that uses a single usb c cable: https://www.huion.com/pen_display/Kamvas/kamvas-13.html but it is rare for bigger pen displays. Without usb power delivery the usb is limited to just 5w output and the display will be too dark to use most of the time if works at all. Some tablet will fallback to lower brightness or with the panel turned off but that varies from vendors to vendors
Unless the product page specifically calls out for usb c to usb c cable you can be pretty sure that it uses 3 in 1 cables.
The device you mentioned has been selling for 2 years now and the latest distro should work out of the box, otherwise this thread might be useful.
