The "paint" inside of a paintball isn't really paint, it is primarily polyethylene glycol which is water soluble and also found in food. They also contain dye. The "paint" doesn't exactly dry like normal paint, it evaporates and breaks down and leaves behind just the dye or a dry paste like residue depending on the paint's fill thickness.

Yes, eventually it will. It however dries to a waxy substance that is easily removed from clothes. Note that low quality and oil-based paintballs tend to stain!
the paint will not dry without being open to the air, so the question is how long will the shell be good and that depends on which paint you have, could be hours could be weeks
