You're wrong. You could Google it first before posting a "correction" that is false. Took two seconds. Also found this Rivals thread discussing it

Not on the 2019 ESPN top 100 list, nor does his ESPN recruit page have the Top 100 logo.
And that's not to say that he isn't worthy of being a Top 100 player... ESPN has given him an 83 rating, and there are 11 guys on the Top 100 list that also have an 83 rating. And he made a single brief appearance at #99 on the list in April.
But he's not on the current list, and so is not currently considered an ESPN Top 100 player. If you're going to take "two seconds" to Google, you should go to the source.
