The perversion of the tie-breaker system of breaking ties only by results between the tied teams means that there's two groups with points distributed in 6-3-3-0 fashion right now with entirely different implications.
While in Group B all teams can still advance (and Belgium with 6 points have advanced for sure in *some* capacity) because last-place Denmark plays a 3-point team (Russia) in the last game, in Group C North Macedonia is eliminated and the Netherlands have clinched first place because those two have yet to play each other. Even if Macedonia beat the Netherlands (unlikey, but eh, for argument's sake!) and Austria and Ukraine didn't draw, Macedonia having lost to both of Austria and Ukraine will always have them lose the tie-breaker for third place.
I hate that system and I have hated it for a good 20 years.
Funny addendum to the absurdity of the situation. Below is the Group B table right now (from
Wikipedia). If Denmark had beat Belgium earlier, Finland would rank ahead of Russia because everybody would be even on three points and you have to break the tie the proper way by goal difference. The result of Game X changing the ranking between teams that did not compete in Game X is beyond bonkers.
