I'm thinking about preordering the iPhone X?

This is going to be my first time preordering an iPhone, I've been checking videos on how to pre order fast. But what I don't get is, what does it mean Store pick unavailable? Does that mean that they're out of stock?

No

Please please please don't get a iPhone. Samsung are the least expensive, the cameras are better, we have an octocore processor iPhone only has quadcore. IPhone tend to break more often they r easier to hack and they are less able to cope with certain data types. I have a Samsung galaxy S3 which is just great. IPhone only matched those stats in the iPhone 6 - 4 years later. If you really want an iPhone, perhaps because the interface is more user-friendly or you prefer the layout, think about it for a second. You are probably going to get ripped off. Do your research before you spend a grand on a phone make sure its the right one for you. If you want a better camera, id suggest google pixel, processor wise id say a Samsung, if you are a gamer and want a phone that can handle a few hundred apps. IPhone specialise in nothing, they are well-rounded but Samsung matched the stats of the iPhone X a few years ago and added to it. Do your homework, kid. Just because they say its the best camera does not mean it is. FYI Apple have illegal child workers in those factories, using heavy machinery and potentially having fatal accidents. I guess that doesn't matter to you cuz you're just looking for a phone.

In the case of a pre-order, it means that they will ship the phone to you, you can't just go to an Apple store and pick it up.

This means you don't have to wait in the blocks long line to try and buy one on opening day of sales, you just wait for the mail man like always.
