And twice the market share of of phones of the next competitor, Samsung.
Now go ahead and add up the marketshare of everyone making an Android phone and compare it against Apple.
Marketshare of the iPhone in North America is highest at about 50%, and is significantly lower everywhere else. Worldwide it is around 20%. Lightning is, and was, a problem to be solved and it finally was. It is not a standard, defacto or otherwise.
EDIT: Also, to your Tesla analogy. Tesla submitted its connector to be ratified as an official charging standard for electric vehicles, which precipitated the sudden lineup of other companies adopting it (primarily to take advantage of Tesla's superior charging network, but, any port in a storm). Apple has been asked—begged even—to do the same with Lightning, to open the connector to become an official standard, but it refused. It actively did not want it to be a standard, it wanted it to be proprietary. Live by the sword, die by it.
