Hello everybody!
Today we will talk a little about the tabletop role-playing game D&D. I want to say right away that I am not a professional, and I only played maybe 5-7 times, and for the easiest classes - warrior, cleric, etc.

So what is a "tabletop role-playing game"? In fact, there is nothing stuffy here, because the only thing that differs from the real game is that each player has to get used to the role of some character, for example, a drunkard, a killer, a courtesan, an emperor, etc. and play it as best as possible.
In this game you will also talk a lot, so you have to try your best to get into the role - if you are playing an emperor, you can't say "Hey man, you have a nice %:#%..", or a courtesan can't say "Congratulations rich Mr. in our secret order of St. Pusia". 

Therefore, to summarize, in this game you can literally do anything: if you want to talk - talk; if you want to tear off the 6th board of the 3rd row in the tavern - do it; if you want to lure a pet - go ahead; - this kind of board game is more about acting and the ability to reincarnate.

Are tabletop roleplaying and D&D the same thing?

We have already dealt with the first concept, so let's move on to the next one - what is D&D. To fully answer what it is, ask yourself the question: "If you can do absolutely everything in the game, why can't I, for example, create a character who creates a million gold coins in his pocket with the power of thought?" - if you read my article carefully, and if I can explain clearly in principle, you guessed that if there is absolute freedom of fantasy, it is necessary to make some system, in which the whole world lives. As an analogy, we can take our world, and it has the laws of physics - this is actually a system.

Dungeons and Dragons Game System - A Brief Overview

So, we have already figured out a lot of things, and if you are here and you think that you are not stuffy - congratulations! You might enjoy playing it too. The first thing you need to master is the cube, there are as many as 7 of them in the set for stuffy DND-shniks. But also, in addition to the 7 cubes, there is always a so-called “Master” who will conduct the game for you, which means that he will always tell you which cube for what it refers to and so on. 

I think the best way to get acquainted with this system will be 3 aspects:

1. Race + class - there are quite a few different classes, races in the game - but that's not what we're here for, right? Race is actually your race, you can be orc, human, elf, etc. And the class is like your profession or affiliation, for example: Orc (race) warrior (class), or Elf (race), Cleric (Class). For more information on races and classes, it is better to use their official site - https://www.dndbeyond.com/ 
2. Using items – Each character has their own set of items. For example, if you are a warrior, then you have a rapier. If you are a cleric, a staff and so on. It is worth paying attention that there are things that are in your hands and there are things that are in a backpack. That's why you can't actually use the things in your backpack.
3. Character actions are the most interesting! I think you have already learned that before any action you have to roll the dice. That is, if you want to hit someone, you throw to hit; if you want to convince a friend to give you a drink for free - you rely on persuasion; if you want to intimidate your friend - you throw in the intimidation. Everything is very simple!

Also, an important point is that if you play a character, you should be that character in the game. That is, you may find some things in life offensive, but your character may do them with joy, so you actually have to play your character, whoever he is.

Is Dungeon and Dragons for the suffocating, or can ordinary people play?

You can play as ordinary people! The main thing is to choose a good master who will patiently choose a character and a world for you, explain the mechanics and lead you into a world of exciting adventures where the only boundaries are your imagination!
