Tie Breaker Scenario

Everyone is talking about how we NEED 3 teams to win to finish week 17 for the Rams to clinch (Washington, Minnesota, Cleveland, SF, Buffalo).

BUT, can someone confirm if we simply need 3 combined wins from those teams the rest of the season? So if those teams all lose this weekend, but three of them win in week 18. We’re fine no matter the result vs the Seahawks, right? Meaning we’re probably at a 99% probability to get in?
