Mm, well, ish. Bodkins are definitely the only type of arrow that will actually go through decent plate armour far enough to be potentially fatal, but if they hit at the wrong angle they aren't going to do much. Also don't forget that the quality of real armour is incredibly variable. Poor quality metal is going to stop a lot less than you would hope, and badly fitting armour is an active hindrance to the wearer.
There's an interesting summary with link online here from Benjamin Rose.
