Worldometers says 62m deaths already happened this year.

I think the 56m estimate of deaths per year is probably what that website thinks happened every year roughly. And is a very rough guess and probably not a fact

Whereas these numbers and worldometers look like more precise/scientific estimates

2021 … 60,119,439
2020 … 59,230,795
2019 … 58,394,378
2018 … 57,625,149
2017 … 56,935,173
2016 … 56,331,837
2015 … 55,822,989

I don't think covid vaccines moved deaths down 4 million given aging population etc.

You might expect 2022 or 2023 to decrease somewhat due to people dying earlier in previous years from covid and therefore not dying this year but at the same time that could be offset by fewer people getting treatment/diagnosis for other diseases like cancer due to everyone trying to stay home and surgery and therapies being cancelled. And therefore cancer or heart disease kills more people this year than pre covid because people didn't have treatment on time etc.

I think vaccines could contribute to the demise of some people but it is blown out of proportion by the people fixated on blaming vaccines for everything and anyone can die at any time in reality. And vaccines undoubtedly save lives as well
