Well, either you started with a rim that wasn't exactly round or true, with not exactly round being reasonably common. There will often be some sort of deviation at the rim joint. Or you missed the count when you first started threading the nipples on, it's easy enough to have that happen. Or whoever picked the spokes out for you accidentally grabbed a few from the wrong box.

Washers on flange or not can affect durability, but they have no influence on initial trueness of a wheel. And washers on rims is not a generally approved part of wheel building, although it can let a builder "save" some situations.
