The reason the button is called "Subscribe" instead of "Download" is because games can update and mod developers can fine-tune their creations. If a mod needs other mods to work, the workshop will also show this list. If a mod needs a DLC to work, the workshop will say so with a big purple banner above the Subscribe button and show the DLCs needed on the right. To download a mod, click on its name and hit the Subscribe button.

The workshop even has save games that show how other players have used the game to recreate cities both real and fictional. This will bring players to a massive library of mods they can browse to find new assets, maps, game mods, building themes, and more. Simply go to the Cities: Skylines game page in the Library and click on the word "Workshop" that sits just below the Play button. By far the easiest way to find and download mods is through the Steam Workshop.
