You need to do like this :

    String ObjectId;
    ParseQuery<ParseObject> playerQuery = ParseQuery.getQuery("Player_info");
                      playerQuery.whereEqualTo("Player Name", "ronaldo");
                      playerQuery.setLimit(1);
                      playerQuery.findInBackground(new FindCallback<ParseObject>() {
                        public void done(List<ParseObject> playerList, ParseException e) {
                          if (playerList != null && playerList.size() > 0) {
                              int score = playerList.get(0).getInt("Score");
objectId = playerList.get(0).getObjectid();
                           }
                           }
                      }

Now you can use score of ronaldo wherever you want :) .

To update the value in table you can do that:

// Create a pointer to an object of class Point with id dlkj83d
ParseObject point = ParseObject.createWithoutData("Player_Info", objectId);

// Set a new value on quantity
point.put("Score", newScore);

// Save
point.saveInBackground(new SaveCallback() {
  public void done(ParseException e) {
    if (e == null) {
      // Saved successfully.
    } else {
      // The save failed.
    }
  }
});
