Ladloy, look up any site that has stats on deaths for the world. It’s all available, for free. Take note of the category of “influenza / pneumonia / respiratory illnesses” and you’ll be surprised at how many die every day. Now compare that to the deaths (globally) due to COVID.
If you focus the stats on countries that have handled covid poorly, like the USA, 2019 flu season killed 20,000. 2020 Covid season killed 500,000, flu is much less deadly.
Pneumonia is not a virus, its a condition of the lungs, so Covid also causes pneumonia as does the flu, legionaires, etc. The category of flu being put with pneumonia and other respiratory illnesses is that it affects the lower respiratory tract.
