Something considerably more than 90% partly because of the time gap between cases and outcome. It used to be something like 14 days even for mild cases because of the tendency of the serious cases to turn so a week to ten days into it. At 40,000 -50,000 cases per day, that is 560,000 - 700,000 who are currently counted as cases but none of whom are counted as recovered yet.
Some unknown number of mild cases aren't counted at all because the people didn't get tested.
Edit to add
From the definitions page of worldometer
"Recoveries = ...WHO recommends following the criteria of [symptoms resolve + 2 negative tests within 24 hours] or [symptoms resolve + additional 14 days], but this is only a recommendation. In some countries, when a patient is discharged from the hospital it is counted as "recovered" even if no test is performed. Some health officials now consider anyone who was diagnosed with COVID-19 three or more weeks ago and has not died to be recovered from the disease. ..."
