What i need to know?
Lots of things. The easiest first one - if you want to make a game by yourself - is how to use a game engine. Some of them allow you to make fairly interesting games without any programming knowledge and come with pre-canned art you can use. Others require you to learn to program in one language or another or will require you to find or create artwork.
I need to be older ?
I made my first game at 9. I know others who started at 5. You're definitely old enough.
Which engine i should use?
This is a highly subjective question. I surmise a huge argument will break out in this thread just over this one question.
A good first bet if you literally have no other experience with programming is GameMaker. Unreal4 has been used by many non-programmers to make games, too. Unity isn't probably super suitable right out of the box, but you can buy add-ons that help.
If you don't mind learning to program, you have more options. Those three are still good choices, though.
I need a team to make a game?
Depends on the complexity of the game and your experience. For your first projects, you should keep it as absolutely simple as possible.
Which lenguage is best for a beginner to learn?(I'm fast learning something there's no problem if is a hard lenguage)
This again is likely to cause a big argument to break out.
The answer depends heavily on why you want to learn. If you're just interested in games and want to make them as a hobby, literally any language will work just fine. Unity will heavily push you towards C# or JavaScript, GameMaker has its own language, and there are engines out there for Python, Lua, Java, or just about any other language you can find.
If you're interested in becoming a professional game developers, C++ is the language of choice in the industry. There's lots of debate about whether it's a good first language or not, though. I say "yes," but plenty of other people will recommend Python or C#.
What type of game i should make first?
The simplest one you can think of. Your first experiments might not even be games at all but just simple tech demos. e.g., figure out how to load a basic level, how to move the player around, etc. Just play around with the engine and get a feel for it.
Where i can find people that can help me on this procces?
Here, to an extent. Being a motivated learner will help. Once you pick an engine - assuming you pick one of the more popular ones - there are tons of tutorial videos on YouTube showing you how to get started.
