Perhaps, but which is more important?

It seems more likely that someone could succeed by simply being lucky, than if they worked hard and never ran into the "right" person, found themselves at the "right" conference, been born into the "right" family or country or situation, etc...

You need a combination of shrewdness and wisdom to exploit opportunities (or to see opportunities where others see none).

These opportunities often present themselves when you work hard.

Based on your name I think you might not be a native English speaker; so just in case you didn't realize, "hard work" is two separate words.
