Yeah, a big difference but with some, like the Aguila Colibri and Super Colibri, the bullets are propelled by almost no powder or just the primer. The bullets are so slow you run the risk of them getting lodged in a rifle barrel. Subsonic ammo is still very quiet out of a rifle but has a muzzle velocity in the 1050fps range instead of 400fps like the Colibri. Also, subsonic is generally very accurate and holds it's velocity better than high speed ammo because it doesn't go through the turbulence of breaking the sound barrier on acceleration and then again when it drops below supersonic speed as it slows down range.
