A lot, I bet. Not sure if you're referring to web ads, or ads in general - but either way, you'll be effected by them more than you'd care to believe. Whilst you might not be clicking on ads, they will, subconsciously, be creating brand-awareness. Have you ever watched Derren Brown's show? The human mind is incredibly susceptible to suggestion. The purchasing decisions you make in just about all aspects of your life will to some extent be determined by the advertising you have been exposed to. Ads create mind-share. When you next need a product or service, the provider that is likely to be the first you think of is likely to be the one to whom's ads you have recently been exposed - knowingly or otherwise. Edit: we are, as Douglas Adams parodied with his Electric Monk, believing machines.
