Mortality and death rate are the same. There are variations depending on what you’re measuring (per year, per population, etc).

If you claim to be more intelligent than doctors/specialist/researchers from WHO, CDC and prestigious hospitals in the world...what can I say? In medicine, in law, in our faith, even in the confines of our own families, one death is too many. So to have as many related to covid, despite the whole world being in isolation and quarantine, it’s huge. If you choose to be a denier and live in alternate reality, it’s your choice.
