Of course, you can't control it. At best you can optimise based on the cards you're dealt in life.
Before this discussion gets too far down the usual track, it's useful to remember the distinction between necessary and sufficient causes.
Is luck necessary for success? At the super-high level, yes. In fact at the low level, yes. Being born in the USA or the anglosphere or in a wealthy country is a massive stroke of luck.
Is luck sufficient for success? No. Ask any lottery winner.
Now to all the other things people list -- intelligence, personality and the like.
Is an anxious drive to achieve necessary? At that level, it would seem so.
Is it sufficient? No. It's not; no matter how ambitious you are it's going to be difficult to transcend some starting conditions.
