Why am I not hitting regular

If the TV weighs 57 kg, it can be hung on a screw. However, if you want a stand that moves it away from the wall and can be angled, it's probably wise to screw it into the studs or use 4 Molly or some suitable screws that grip well in the OSB/Plywood behind the drywall.

Wall mounts only function to tilt the TV 10 degrees down, which we will never use...

A regular wood screw in plywood probably holds just over 200kg load, use two for extra safety.

Took 6 pcs, two in the wall and the rest in the board, hung myself on it weighing 80kg and it managed to hold me so now the TV is on the mount 😂😂

yeah, it's probably hanging quite safely

I have a stud finder that is magnetic and it only attaches to where the screw heads are... I'm thinking if it was a metal stud, the finder would attach along the entire vertical length and not just at single points.

The distance to the metal stud might be too great, especially if there are double sheets. A strong neodymium magnet might help, at least if there are single sheets.
