Usually the leader at the top of the Bundesliga table is Bayern Munich but now the best players Bayern Munich have gone to another club so they can't afford to get another win and it's very difficult to catch up in first place again. However, Union Berlin is still not the winner of this Bundesliga because there are still several matches that might change the position of Union Berlin.
Bayern Munich and with several other teams actually still have a chance to catch Union Berlin points because the difference is not too far and the number of matches in the Bundesliga is still very large, but if Union Berlin continues to have a very high consistency in every game that is left, that too will make it difficult for other teams to chase points this season.
