This is because the bar does not represent health points. The bar you are looking at (the one obtainable by going to the "Champions" tab on your profile page) is called "defense power". Ezreal gets more base armor and armor per level than Vayne and more base health regen. His kit is also very slippery (he has a lot of escape and kiting mechanisms) which makes him able to defend against attackers easier. Think of that bar as "survivability" instead of "defense power" and it should make things more clear!
