According to the wiki if you start your 3rd victory lap your character will automatically turn into The Lost.
I haven't unlocked the character yet and I was wondering what will happen if I start my 3rd lap. Will I turn into The Lost and maybe even unlock him? Or will I just keep playing as my current character?

According to the wiki you linked:
then no, you can't unlock The Lost in that way.
But I don't see why you won't be turned into The Lost even if you haven't unlocked it yet. It's a fixed character, like a daily run or a challenge.
