Because water is heavy, the deeper you go down, the more water that is above you pushing down. Think about it like if you were to have 5 gallons of water on top of you compared yo 500,000 gallons of water above you.

Pressure in water is exactly dependant on depth. Every 9.81m of water bring your 1 Bar of pressure with their weight pushing down.

Oceans are deep (citation needed).

A small extra: saltwater is a little more dense, making ocean water a bit heavier. So at the same depth the ocean has a slightly higher pressure than in fresh water.

Imagine that you put a sack of flour on your head. It weighs about 5 pounds so you feel 5 pounds of pressure on your head. Now, put 100 sacks of flour on your head. You feel 500 pounds of pressure.

In the depths of the ocean there is way more water above you pushing down and creating pressure.

Basically because there’s so much more water on top. Think which would have more pressure:
You laying down with two bricks on your chest vs you laying down with 1,000,000 bricks on top of you.
Replace the bricks with water and there you go.

The weight of the water above you increases the deeper you go and this increases the pressure you feel on your skin.

The same applies to air, and can be measured with air pressure meter.
