I’m doing this pattern and it says to meansure 3 inch above the guesset before starting decrease. Is the gusset where the V starts?
Yes, where you start doing the increases.

I’m not 100% sure, but it seems to me that worded this way it would mean 3" from where the gusset ended, which would be where you quit doing the increases for the gusset. So it would be not the beginning but the top of the vee that you measure from. Most gussets start not far from where you finished the cuff and 3 inches from there would probably be too soon to begin the decreases for the end of the mitten, but that could depend on the way they shape the mitten.
It makes sense to me too that it would be 3" from where the gussett ended.
