Does anyone know How "impact" is relevant to drill bit or just marketing gimmick?

"For impact drivers, the best drill bits are specifically labeled "Impact Rated," featuring a 1/4-inch hex shank, shorter length, and a torsion zone to absorb shock, preventing shattering; standard drill bits can break under the sudden, high torque of an impact driver, so always look for impact-specific bits, especially for drilling pilot holes."
