What are PGP Keys?

In asymmetric cryptography (just like in bitcoin) you have a key pair. A private key that you use privately to sign stuff or decrypt encrypted messages. A public key that can be published publicly that others use to verify your signatures or encrypt messages that only you can decrypt.

What are those numbers that people display on their profile or signature?

It can be a lot of things!

What are Signed messages and how do I create them? Notepad file? I'm really lost on that part.

With an application that has the option to sign messages! PGP is installed on most Linux distros by default and Kleopatra works on windows.

I understand that the use of PGP is essential in the Bitcoin community

The only use case it has is when people want to verify signature of wallet binaries, otherwise it is not really essential.

For me it is, because the support team for the freebitco faucet uses bitcoin signed messages as the last last last resort in order to recover a lost account. (Idk if this is even what you are talking about.)

Although signing a message with a bitcoin key (from your address) shares some similarity with PGP but they are not the same thing. You don't need an additional software to sign or verify bitcoin messages, most popular wallets like Electrum already have that option and there is not much to learn since the process is pretty straight forward.
This is how it looks like in Electrum, you just fill the boxes and click the appropriate button:

There's a quite old but extensive tutorial about signing messages, here: How to sign a message?!
If your wallet isn't covered by the guide, try to find a button/menu that resembles the "sign message" features shown in the tutorial. Most non-custodial wallets have it.

I understand that the use of PGP is essential in the Bitcoin community, and I want to start making proper use of it.

It looks like pooya87 has given you what you need, but in case you're still interested in learning PGP, here are some waypoints:

• The standard that describes the modern version is known as OpenPGP and is documented in RFC 4880. It's probably too technical for most people to find useful, but it's good to know what the authoritative reference is.
• The most popular implementation of the OpenPGP standard is known as GnuPG (GNU Privacy Guard, sometimes abbreviated GPG) and is available here. It's already included in most Linux distributions.
• The documentation for GnuPG is comprehensive and will cover just about any question you could possibly have. If you're not sure where to start, then I recommend going through the "GNU Privacy Handbook" (HTML or PDF).
• GnuPG is used from the command line. Modern users may find it easier to use one of the different frontends available (like GpgFrontend or Kleopatra).

Hopefully that gets you started!

Thank you, this is very useful information. I have recently started to understand cryptocurrencies and when I come across similar topics, I am always glad that there will definitely be an answer.

Thank you for your time, this is very useful information for me too. I'm still discovering some new things here that I didn't even think about before.
