Content is actually created by you. SM is a sandbox. That means it has game rules designed to offer you a frame in which YOU paint. Said rules vary wildly from version to version so unless you want to play multiplayer, I suggest you start with an older version, something that doesn't start with 2. That is because between last 1.9 version and 2 game got huge changes that are not over yet, so in the latest version not everything fits. Some parts of the game are new and shiny but other parts are obsolete and are still in game, waiting to be changed and fit in.
Before 2.something versions there were no catastrophic sudden changes and features and balance changes were introduced one by one and the game is definitely more coherent.
Of course, game has a few content even if you don't create it, but that is just to let you get a feel of what you want to make. Default Pirates are dangerous only for the unarmed beginners, default station models are few and get boringly repetitive fast, pirate stations will scare you hard but are actually weaker than most players' ships in damage per second, shields and shield regeneration and so on.
Of course, it is up to you, the player, to create or download ships and stations and make them available to your game to use instead of defaults and then improve your self to build things that can win against your own creations that you gave to your pirates to use.
Crafting is easy and obvious in 1.9 versions, to get resources you can mine planets and asteroids or hunt pirates or buy from game's shops and resell to other shops for up to 20% profit or claim pirate and trader stations using their built-in faction modules then take and sell the blocks they are made of... This game is a sandbox, you are free to be who you want to be, do what you want to do. You can make your map a Star Wars entire universe or you can just be one of the pirates killing and looting the game's honest traders.
If you don't like building what you use with your own hands and the help of a very good embedded build-helper, then I am afraid you either need to join a server others built either choose another game.
