GOOGLE'S ADVERT ALGORITHM - DOES IT WORK?

All the talk is about how GOOGLE uses our activity on their websites to decide on what adverts we see online. GOOGLE now publish your "personal info" that originates from their systems and their advertises. They use this to decide what to advertisements to push to you.

So now I know what picture GOOGLE have on my interests based on "48 factors" - Rugby and South Africa do appear in the list and clothes and shoes don't. So why do I continually see adverts for the most ridiculously designed shoes and clothes?

Their factors do tell them I am male and 65 Years+. Is it just that GOOGLE collect more data than they can use or are algorithms not up to it?
