Any matter going through you with that much mass is going to cause damage no matter how fast it goes. Billions of particles called neutrinos are moving through you right now as you read this but they are around 100,000,000,000,000x less massive than a hydrogen atom
Pure theory, likely never ever going to be real, but could a bullet move so fast that it goes through someone without even damaging them?
No, but if it travels fast enough it would disintegrate and you could argue the resulting plasma blast would be what actually damages the target.
Relevant XKCD (in video form).

Turns out Gamma Ray Bursts are just distant peasant railguns
Not really applicable but think there could be a small chance it would quantum tunnel through the person but that’s such miniscule chance.

Define damage. Can it pass through the middle of organs? Sure, if it hits just right. But that’s not so much a question of speed.
You’d need a pin needle shape to have a chance of piercing an organ without causing lasting damage, but it will probably break on impact
Just like ghosting through it or something
Only in anime.
