Let's do a bit of math.
Atlanta Journal-Constitution reports there are around 50,000 uncounted absentee ballots left, and they are in heavily blue Fulton and Chatham counties.
Trump leads by 14,000-some votes.
Let's say 3/4 of the uncounted votes are for Biden.
Presently, Biden has X votes.
Trump has X + 14,0000
Finished count, Biden will have X + 37,500 votes.
Trump will have X + 14,000 + 12,500 votes.
Biden will win by 11,000 votes.
Nothing's certain, but I'd say Biden's chances are pretty good.
This should, at least, reduce the sweating factor in Arizona, in Maricopa County.
