Water weight is your body storing water. Calorie weight is stored as fat.

Really want to turn your noodle – when you lose weight by burning fat, you exhale the weight as water. So calorie weight is in some ways water weigh anyways

On the scale, no difference. A pound is a pound. In terms of long term weight loss, fat is relatively slow to be lost. At a simple level, you need to burn 3500 more calories more than you eat/drink to burn a pound of fat. That’s something like running a marathon per pound. On the other hand, water weight can fluctuate quite quickly. Your body may retain a couple of pounds of water from eating very salty food, which you’ll then easily lose by peeing it out when you don’t consume as much salt.

“Water weight” is simply the weight of water in your body.

Water is stored and used in your body, but it’s way easier to get out than energy stored as fat, or the weight of your body tissues. You can take a diuretic, or just sweat, and you lose the weight of water. (This is often not healthy, because dehydration can do a lot of bad things to a lot of systems.)

When you drink water, it stays water. It might be in your blood or sweat glands or such. But it’s water and leaves as water (urine, sweat, tears). Proteins and fats and carbs can be dis-assembled and repurposed so that they are part of your body — a fat cell, a muscle fiber, an organelle — and convincing your body to lose that kind of weight is a lot harder. You have to (literally) burn it – which is why we think of that weight as associated with energy (calories).
