If you are using Wi-Fi on an iPhone, do certain tasks use your data plan still?

I know using Wi-Fi is very efficient to slow down your data plan usage, but does it completely eliminate using data out of a monthly data plan on phones or does it just cover part of your everyday tasks? Say I was on Wi-Fi and watched videos all the time, downloaded apps all the time, etc. And I was also under Verizon 4g. Would the Wi-Fi completely cover all of that browsing and usage or would any of the data "leak" from my data plan?
