Rubber bullets and tasers can be lethal.
Actually, people have died after being tased; but so far nobody has been successful in proving the Taser caused the death*. Rubber bullets on the other hand have unequivocally caused death and the people who sell them usually include warnings of the potential for death or serious bodily injury. So that is one way using a taser isn't like using rubber bullets. In either case, the people using those items usually receive specialized training on their appropriate use.
*There was an incident where a guy got tased and then fell and struck his head, causing him to die from the concussion; but none as a direct result of a taser.
