Double your life total. Target opponent loses half their life, rounded up.
However, no where in gatherer does it specify when at 1 life what happens. I guess it is assumed and maybe I come off as a noob. However, even though I know I was going to lose this game. I would think half of 1 is .5 and then rounded up is 1 again. Therefore, losing zero life and then the caster of this card doubles their life total.
Could someone please elaborate why when your opponent or for my instance why I would lose the game from this card?

You actually have the math right in your question: you lose .5 life. The card says "but round that up" so you do. You round that to 1. So, you lose 1 life.
You seem to be misreading it as "your life total is halved rounded up" which is not the same thing. The rounding is done on what you are losing, not what your life total ends up at.
For the purposes of Revenge, "half" of 1 life, "rounded up", means 1 life (see also C.R. 107.1a). Thus, if the targeted opponent has exactly 1 life, Revenge makes them lose 1 life, bringing them to 0 life. Here, the amount of life lost is rounded up, not the resulting life total (C.R. 107.1a). See also Chainer's Torment and Torgaar, Famine Incarnate.
As the card states:
