I introduced D&D and TTRPGs to all my friends and have been the forever DM for 4 years now, and I highly advise you to stick as a player at first. If you want to be a DM, play the game and try to join games of different DMs, take mental notes of what things they do to make you enjoy the game, what tricks they use for storytelling, etc.
Also, if you want to tell your stories on a game with no disturbance, I am sorry to say this, but it's doubtful that you will experience what you planned in your head. Players can and will derail the campaign. It's not something bad and is more like a core feature of D&D. One of my player groups' favorite sessions was when they accidentally killed a noble on what was a simple meeting for taking a basic monster hunt quest so they could try their new items and level 3 abilities and spent 3 hours struggling to hide the body while distracting the staff, other customers and local police.
Also also, personal preference but the rule of the cool over core rules every day.
Also, also, also, try to make a system to keep track of players and enemies because 3 level 2 players fighting against some goblins is easy to track, but a party of 5 fighting against a horde of monsters can turn very hard to track very fast.
Also, also, also, also, don't pressure players into doing what you want, but have strict rules. For example, some of mine are:
No murder hoboing unless everyone agrees, and you will bear the consequences.
Don't be an edge lord and accept you are not 'THE' main character but one of the main characters. You will have your moments, but not all the moments.
If you want to betray the party or play a character that will do that, talk with other players first and get their consent.
But if you plan on hosting games in a game shop or a club, you need many more rules than mine and act much stricter on them. I only DM close friends and for reasons. Dming for a group of strangers can be a nightmare, and you must be ready to ban someone for reasons you think you might not need to, like basic hygiene or trying to flirt with another player even though they reject your advances and are uncomfortable with it, or you know, simple unneeded politics and open racism against other players.
