231,186 PointsIt's not just any specific web server you can make requests to, but the same server that your page loaded from. A request made to any server other than the one that hosts your page is a "cross origin" request.
This kind of a request might be possible, but only if the server allows it and you provide extra information in the request header.

231,186 PointsIt's the other way around. You can make multiple requests to the same server your page loaded from. Those are all allowed by the "same origin" policy.
You only run into trouble when you try to make requests from some server other than the one your page is hosted on.

231,186 PointsRight, except only the same server. Other servers in the same domain are still considered cross-origin.

231,186 PointsThat's what this video lesson is telling you. To access other websites, your host site must act as a proxy, or your requests must contain CORS information in the header (and the other server must allow it).
It is considered "cross-origin" because the server you are making the request from is not where your page was loaded.
