If you define 'lucky' as someone for whom physics/statistics do not apply then you make it a pretty meaningless term for the real world.

or better chance of finding money on the street or so on.

This is what the article is talking about - the chance of money being on the street stays the same, the 'lucky' person is more likely to spot it.

Sorry, I was not clear. I meant that the there will be money in the street. Not that they will find them. I will edit my post.
