"Accidentally winning" is pretty much a hall mark of a Gary Stu/Mary Sue/Chosen One.
Good shit always happens to them.
Their character arc is always that they have to believe in themselves, not that they need to train extra hard. That's it.
The first time Neo fights anyone in The Matrix he basically beats Morpheus. So you're being disingenuous about that.
He could've smashed Morpehus' face in, he chooses to hold back because he is uncomfortable.
That's basically all this character type has for a challenge ... the uncomfort of how powerful they are and the burden of being "chosen". They will generally rebel against this at first, but eventually get talked into it.
This shit is standard archetypal story telling.
