I just got an v6 acura tlx shawd with 60,000km on it (first car ever) and I couldn't help but notice that when I reached 120/140kph that there was some sort of vibration, I'm not really mechanic savvy at all, wondering if I'm in any danger behind the wheel of this vehicle, note this car was straight from the dealership and had a safety check

Know design issue with the AWD TLX. See "vibration issue" topics in this forum.
Basically, the car resonates under certain conditions, depending on the rear differential / propeller shaft alignment tolerances (and probably other issues). This will never be fixed. Either lear to live with it, or try to return the car if your dealer will let you!

It's just confusing because my dad had the same car and it never happened with his

This is a known issue for the TLX. However, not all the TLXs vibrate. Check your wheel balance as well.

Some have the vibration issue and some don't. My 2018 does not, but others I test drove have it.
I think the car's chassis is prone to vibration - and then it depends on how much the specific parts installed. Look at some of the other threads and the service bulletin and you will get a better understanding. Even honda engineers can't seem to fix the problem.

Seems I read it's most prevalent on SHAWD, not so much on FWD.
