So then why are all other sources showing much lower infection rates?
I can't find what the date ranges are for John Hopkins' data. OurWorldInData says Feb 2020-Aug 27, 2021. The CDC link from GP says February 2020–May 2021.
Your links give the fatality rate for confirmed cases, which is basically useless. For the most part only people with significant symptoms bother to get tested and counted as cases, which skews the fatality rate artificially high. What matters is the actual fatality rate over all infections. The CDC documented their estimation methods on their site if you want to get into the details.
