If we spoke BaronSpeak, we would assert that the voters have spoken, and the Democrats are cleared hot to undo the filibuster, unpack the Court, and pass whatever they want to .... because they can.
But, I am not Baron. Democrats will honor the filibuster, and let the moderates (Manchin, Collins, Romney, Markowski) run the Senate.
51-49? 50-50? Not much difference. It means talk to your fellow Senator and find common ground.
