I am correct.

Look at white hoodie on this guy. It seems hit also, but travels in the direction I am talking about.

There is a very clear and distinct procession of events here. Railing, white hoodie is grazed and moved, man is hit.

Also, an object hit by a bullet, if the bullet enters/exits that object, will disperse a puff of material on the side HIT by the bullet. The entry side. Not exit side.

The bullet went THROUGH the railing, grazed the white hoodie, and ended up hitting the mass of the final man on the left.
