I think the big problem I see here is a lot of people focusing on percentages instead of actual votes. Georgia's got about 150k votes left to count, all urban votes, with only a 40k lead over Biden. In PA, there's a similar thing going on, but with 1 million ballots - we've seen maybe 300k posted since then, and Trump's lead has been cut in half, so there's still a ways to go.
They can definitely still be losses, but there's good reason to be optimistic.
