So this is a simple question. I found some code that uses "@" and I looked it up in the matlab documentation, but I did not find it to be really helpfull. Can somebody explain to me what it does and when/how I want to use it ?

Hi,
You might have seen function handles.
A function handle is a MATLAB® data type that stores an association to a function.
To create a handle for a function, precede the function name with an @ sign. For example, if you have a function called myfunction, create a handle named f as follows:
>> f = @myfunction;
Now if you have a function like
function y = computeSquare(x)
y = x.^2;
end
>> f = @ComputerSquare;
>> a = 4;
>> b = f(a)
will give
b = 16
Please go through these 2 documentation links which very clearly explains about function handles.
Yet another use of the symbol '@' is as class folder designator. An @ sign can indicate the name of a class folder, such as
\@myclass\get.m
See the below link for more info.

Well, this answer that was given (6 years ago) is more confusing....

What makes you think it is confusing? (let alone more confusing)
And your answer does not mention important details that the accepted answer provides.
