I touched a hot metal spoon and my skin ended up looking like a bubble, I’m curious why it’s the total opposite of when i cut myself.

You didn’t cut it…. so it won’t be a cut. When you burn your skin the heat just kills the skin cells. It doesn’t slice them open.
The blister is your body’s way of healing. It fills with liquid to keep the bottom layer cool and moist while it develops into new skin. The top of the blister is all dead skin (don’t pull it off yet).
When you burn yourself, instead of undergoing controlled apoptosis, the cells undergo necrosis. The skin cells are rapidly dying and their membranes break apart, spilling their intracellular contents to the surrounding cells. This can damage the neighbouring cells and triggers a localised inflammation response, recruiting white blood cells and ultimately leading to the formation of blisters.
