I tried the seed you provided on a world in the PC/Windows version of the bedrock version. The trail ruins in question do indeed not generate, however I am thinking that the video you showed is still in the beta version of 1.20 and as such some world generation was not final yet causing it to change.
Have you tried using the /locate command? You can locate trail ruins that way. I will say that using the locate command within the same seed gives a different set of coordinates but they still do not generate. I've noticed this with my survival world, I was not able to find any trail ruins in newly generated chunks, however I may just be unlucky.
In the seed you provided I was able to locate trail ruins at 832 ~90ish 704
