How to get the number of github repositories and subscribers?

Question

Java

Good afternoon.
I get a list of random github users, select two users from there. You need to get the number of subscribers and public repositories. However I receive each time - "0".
I use Retrofit, github API

final Call<List<GithubUser>> call = service.getListOfUsers(new Random().nextInt(4000000));
                call.enqueue(new Callback<List<GithubUser>>() {
                    @Override
                    public void onResponse(Call<List<GithubUser>> call, Response<List<GithubUser>> response) {
                        if (response.isSuccessful()) {
                            GithubUser user1 = response.body().get(new  Random().nextInt(30));
                            GithubUser user2 = response.body().get(new Random().nextInt(30));

                            Picasso.with(MainActivity.this).load(user1.getAvatarUrl()).into(userAvatar1);
                 
                            userData1.setText(user1.getLogin() +
                                    "\n" + String.valueOf(user1.getFollowers()));
                              }
                        else { }
                    }

                    @Override
                    public void onFailure(Call<List<GithubUser>> call, Throwable t) {}
                });

//описание запроса 
@GET("/users")
    Call<List<GithubUser>> getListOfUsers(@Query("since") int number);
//для генерации POJO класса использую <a href="http://jsonschema2pojo.org">генератор</a>

for the generator I use the following form

{
    "login": "user",
    "id": 66742423,
    "public_repos": 0,
    "public_gists": 0,
    "followers": 1,
    "following": 0,
  }

Tell me why the list that came from the server does not contain data on the required parameters (contains "0")?

Answer 1

since does not return full user info, 0 because primitives cannot be null.

{
    "login": "josh",
    "id": 137,
    "avatar_url": "https://avatars.githubusercontent.com/u/137?v=3",
    "gravatar_id": "",
