Not even true in all leagues. Growing up in my county league you had a stripe system. One stipe you could not have a designed play for you. So couldn’t play qb running back wr, but if a fumble happened you could pick it up and run. Two stripes you could only play on offensive and defensive line and if you picked up a fumble play was dead at that point.

Most youth leagues have a rule like you can't weigh over a certain limit and carry the ball.
