Anakin, at age 9. relied on his instinct and intuition. An established natural force ability as seen with Obi-Wan's quick lesson to Luke on the Falcon on wearing the helmet with the blast shield down so he couldn't see which enabled him to deflect the bolts from the little droid. And the line "your eye's can deceive you, don't trust them". Same way Luke was able to bullseye Womprats in his T16 and shoot the exhaust port on the Death Star in the X-Wing without the aid of his nav computer. But he was already "the best bush pilot in the outer rim" according to Biggs. He was 19, so I assume he was flying for quite some time already.
And yes, while Anakins heroics in the ship were a bit much, he was on auto pilot that brought him into space to the battle. Plus he had R2 to help out. Still a little far fetched, but more thought out than anything in TLJ. And then little Ani trained for 10 years at the Jedi temple to learn how to manipulate all the forces other abilities. From 100's of the Jedi's best trained masters. Neither Anakin or Luke were levitating rocks, force communicating, resisting mind probes form someone with raw power, using a lightsaber like a trained master until after being taught. And even then it was years of practice not after a few days. Rey took on Kylo like it was nothing, Luke got his ass handed to him by Vader. Yeah yeah, Kylo was injured by Chewies amazing bowcaster that Han had never picked up or fired in their 30+ year relationship. At least JJ used juxtaposition to make it known Keylo was in pain. From Rian we got a rebel tasting the ground to let us know it was salt.
