Since sorcerers use magic from their bloodline, what’s the difference between someone who has “the Gift” and a normal sorcerer?

Since sorcerers use magic from their bloodline, what’s the difference between someone who has “the Gift” (not entirely sure what this is I’m gonna search it up later) and a normal sorcerer?In the Realms, "the Gift" is the innate ability to wield magic (arcane magic is "the Art"). Not all mortal beings have it. Some can neither 'feel' magic (until its effects hit them) or work with it. Just as some people can carry a tune, and others can't.#Realmslore

(No one can be a sorcerer who doesn't have the Gift.)#Realmslore
