The American Election is not over and done until ALL votes are counted...
Yes, that's true now and has always been the case; I believe this year that date is planned to be 14 December. However; the election is over. The decision has been made by the American voters and Joe Biden is the president-elect. Unlike what's claimed by millions of Republicans and Trump supporters, the mainstream media calls the election when it's certain that one candidate is projected to have the most electoral votes. This is perfectly normal, and if I remember correctly, Trump was perfectly fine with accepting that call in 2016 when the media said he won, even before he reached 270 electoral votes. And Clinton conceded the next day. The fact that without this system the populated centers would always pick the winner, is worthy of a whole other discussion...
