Just by downloading tor I will be able to access those links that lead to resources? Or do I need to do anything else? Tor will just let me visit those websites?
Yes, Tor will allow you to directly access any website you want, those on the clear web, and even websites on the deep web, which are more commonly known as onion websites because their links end in .onion instead of .com and so on.
You do not have to download anything else, even though it is suggested to do one thing, and that is to go to Tor's settings after downloading it, to choose "privacy and security" and to pick the "Safest" security level out of the three options available.
However, bear in mind that searching and using the Deep Web is not exactly easy in a sense that you cannot find whatever you want withing seconds just like using Google search. You have to browse through hidden wikis containing various links, realize that half of them are broken, and then browse some more.
Also, even though I myself have never ordered anything from the Deep Web and am not planning to, either, I found long guides you should read before ordering anything, such as pieces of advice on how to be careful, on what to do and not to do when ordering anything, and on how to use cryptocurrency. So you will have to do a lot before engaging in anything. Some of the offers there may also be scams, some sellers may be FBI honeypots, and certain websites may have their cloned versions created by scammers just for the sole purpose of phishing and getting your password.
The purpose of this is not to scare you, but for you to understand what you might be getting into.
