You can say the same of almost everyone that is successful in the world. Also, Steve didn't turn himself into god, people did. Ambition and determination play a huge role in successful people's lives (depending on your definition of success), but LUCK is always a huge factor.
For example...
0.) Lincoln wouldn't have become President if he had given up after a few election losses, and we could make an argument that slavery in America would have taken much longer to abolish or not at all without his leadership. Perhaps Lincoln was mentally ill to run so many times instead of gracefully accepting his loss.
1.) Elon Musk would never have cofounded SpaceX & Tesla would not be possible without him betting his financial future on the company. But you could make a similar statement that Elon wouldn't be who he is today, if he hadn't left Sooth Africa, if he hadn't stumbled upon SV, etc.
2.) JayZ would never have become what he is today, if he had gotten busted or shot in his younger years when he was dealing drugs.
3.) Nelson Mandel wouldn't be who he is today if he had given up on his ideals and dreams of the future while serving for 27 years in prison.
4.) Justin Bieber wouldn't be the most popular musician alive today if he(his mom) hadn't uploaded a video on youtube that resulted in his being recruited by some music manager and promoted just as social media and sharing where becoming the part of everyday life. He'd just be another guy that saw singing as a hobby or gained only regional fan following if he pursued his passion.
TL:DR -> Almost everyone you know, respect, admire or don't would have been an "absolute nobody" if it weren't for certain circumstances favorable/unfavorable in their lives.
On a more generic level, you could say if a person's biological mother hadn't consummated a relationship/fling/marriage with that person's biological father, that person and everything s/he has accomplished wouldn't exist.
