'Lambda functions with "=" capture and memory usage

In my mind when I create a lambda [=]{...} all variables from parent function clones to the lambda.

So the following code will use too much memory because variables a...z will be copied to lambda function:

void foo() {
    long double a = 0.123456789;
    long double b = 0.123456789;
    long double c = 0.123456789;
    //.... 
    long double z = 0.123456789;

    auto val = [=]() {return a+z;};
}

Is not it?
