Consensus means "general agreement".
It doesn't mean everyone has to agree.
An opinion or position reached by a group as a whole. The group as a whole does not agree on an opinion or position; quite literally, yes, it means that everyone has to agree. Thus, #TWDMWYTIM. Further, for specific language for the legal definition (which is simply a more concise description, really), "A decision achieved through negotiation whereby a hybrid resolution is arrived on an issue, dispute or disagreement, comprising typically of concessions made by all parties, and to which all parties then subscribe unanimously as an acceptable resolution". I shudder to think about how it would impact the justice system if concensus were still the term used and it didn't mean that the jury had to be in complete agreement. The phrase you are looking for is majority agreement, based off having a majority (having more opinions on one side of an argument than the other). There's still a significant minority that disagrees with this option.
