Yes, Jobs dropped out because he didn't want to spend his parents' money attending college (they were not wealthy and could ill afford his tuitions and living expenses).
There are similarity between the two: Jobs cofounded Apple, the real technical brain behind Apple was Wozniak. Ma cofounded Alibaba, the real technical brain behind was someone else.
A successful business person is mostly not a technical genius but someone who is able to sense opportunity and figures out a way to take advantage, an integrator. Most technical genius cannot but an integrator can.
