"Trust in AI is down globally from 61 percent in 2019 to just 53 percent, per the Edelman poll." I am having a hard time finding exactly what this number means

"Trust in AI is down globally from 61 percent in 2019 to just 53 percent, per the Edelman poll." I am having a hard time finding exactly what this number means in the linked report. I see a "50" for AI on page 13 - is that the number that used to be 61?
