A person's success is inseparable from their efforts, but it is important to have luck.
It depends on destiny. This was like the rebellions against the emperor in the past. If society was peaceful, it wasn't effective no matter how much effort you put in. But when times were really troubled, a shoe seller or even a beggar could become an emperor.
It was true that Yang Ming's initial success was entirely based on luck, but it was inseparable from his benevolence. If he didn't chase away these two punks, Zhang Yuliang and the blond yob, the old man in the street stall wouldn't have given him a pair of magic contacts.
If he didn't help Fang Tian, he wouldn't have learned martial arts. But a person can't do anything based on luck, and Yang Ming knew this, too. He learned the skills from Fang Tian diligently. He even started to develop his own team.
