Luck, or Dragon ;) So it would still be the help of others if so haha. It was always up in the air whether the weird astral looking green storm that gave them a tailwind out of Loguetown to Reverse Mountain, and if the lightning bolt that saved him was the influence of Dragon with some legendary fruit (Like wind dragon of the east power, you know, or something awesome like that. looking to the east and sending his winds to check up on Luffy haha)

Since he saved the survivors of Goa from being burnt by using the wind tunnel to lead them to his ship, we know the wind was indeed his but we still don't know if it also grants him the power to generate a storm with lightning, like how Croc can start a sandstorm that becomes passively generated without his influence, maybe Dragon can create the right circumstance for a thunderstorm.

But yeah who knows. Buggy did come pretty damn close. I love how top-tier bosses utterly tromp Luffy the first time, its his perserverance and tactical brilliance as pure instinct that brings him through..Magellan and Croc basically did kill him, but left him within an inch, whereas Buggy would have finished it in one fell swoop without messing around..

As some pointed out, if Kuma or Aokiji truly felt like taking him out they probably could have trounced him in one shot
