The gravel and sand filter out smaller particles from the water
With a fine mesh sieve.
To separate sand, gravel, and water, you can use a filtration method. Pour the mixture through a filter such as a sieve or cloth to separate the sand and gravel from the water. The water will pass through while the sand and gravel remain on the filter.

You're talking about driveways, right? As in your zoning says you can have either a concrete drive, an asphalt one or a sand & gravel one? Gravel is crushed rock, and they say "sand and gravel" because gravel almost always has sand in it. Crushed loose bedrock would be fine.
Yes, sand has fine particals, gravel is much larger.

Gravel, sand, silt, and clay are classified based on their particle size. Gravel has the largest particle size (greater than 2mm), followed by sand (0.06mm - 2mm), silt (0.002mm - 0.06mm), and clay (<0.002mm). Gravel is coarse and drains water quickly, while clay is fine and retains water.

The amount of time that gravel can retain water will vary depending on its state. Fine gravel will holder water for long as opposed to coarse gravel.

Gravel can be composed of varying sizes of stone, sand, and fine dust, with the coarse stone measuring up to about 2 inches. Large stone is often referred to as ballast or sometimes, pit run. Even larger stone (6" to 24") is called rip-rap. Rip-rap is used to armor the soil to prevent erosion from water runoff. If you are using boulders or rip-rap, then gravel would probably be considered a fine aggregate. But if you are using gravel under a new sidewalk, say, then gravel would be somewhat coarse compared to the sand and fine dust in it.
Water typically travels faster through gravel than sand soil because gravel has larger pore spaces that allow water to flow more easily. Sand soil has smaller pore spaces which can slow down the movement of water.
