Woah I didn't know about Linux support on Android tablets sounds interesting!

It's promissing for sure. To set expectations, it's early days, and other than for basic terminal usage it's mostly a hackish experimental thing coming to Android 16.. But it works and I have seen folks with powerful mobile phones running full blown desktops, plugin their phones to external monitors, coding, running containers and the whole thing.
This comment is calling bull on the claims made. Did you try it personally?
I can't say anything about the GUI interface in the video and haven't run a full blown Desktop like this myself. I just grabbed the first video I found on Google. But yes, I'm running Linux locally on a Pixel phone since the Beta. Like I said bellow, it's still at early stages for Devs to work in, but it works. And before that we already had Termux:X11, Andronix and several other solutions on different stages if maturity.
Here's a more reliable source running Doom several months ago (I haven't done it myself either): https://www.androidauthority.com/android-16-linux-terminal-doom-3521804/
My honest opinion is, even if the video in question is bogus, it's just a mater of time until what we have surpasses what it's being shown there.
