As of May 12,2020
83,425 Americans have died from Covid19 - 28.5% of the world's death toll.
Updates to follow.
I'm not sure where you got your data, all sites are running one day behind and none, including John Hopkins University (JHU) is showing that on May 13th. Todays' number on JHU's Dashboard is 82,389, which is actually for the 12th.
Unfortunately, JHU doesn't post historical daily death numbers as far as I can find, meaning that you must catch each daily report late in the day in case of later adjustments, or rely upon different, less reliable sites for trends.
You are right to be looking at the number for deaths as case numbers are wildly unreliable and useless in future predictions.
There's a good chance that tomorrows' total for today will be north of 84,000 based upon a 7 day running average.

Edit for correction: JHU indeed posts the death data, just not on their "Dashboard", however it's linked beneath the "case" data. It's hard to find and not intuitive to use.
