GDP alone means nothing! Basically, GDP is the sum of everything that was produced and provided in Brazil.
You have to use the context in which this GDP data is inserted.
I'll give you a very simple example to help you understand:
Imagine that you are a country and with your work you can live well. Your GDP is X (production).
At some point, your cost of living starts to rise (inflation) and you need to work more overtime or even find another job in your free time, so as not to go hungry.
As a result, you produced twice as much, your GDP is 2X, but your life has gotten worse and is more difficult.
It's a simplistic example, but it's enough to take GDP off this pedestal used by people who know little about the subject, but watch too much TV.
