The normal seasonal flu has hundreds of strains with highly varying mortality rates. That's why flu shots have to change every year. Experts try to guess which strains will be prevalent in the coming year. Some of the strains have mortality rates as high as 3%, but their infection numbers are only a small fraction of the total. Covid's infection quantities are also dwarfed by the flu, making it equivalent to a bad strain of the flu. My source is the daily cdc reports, which can be found on their website. The high projection numbers you're quoting all have dubious sources, yet they are constantly referenced by the media, because they bring in viewers.
