7% MSCI World realistic?

In a nutshell: This calculator here: https://einfachberechner.de/sparplan/?start=0&rate=1500&jahre=32 shows that if I invest €1,500 a month for 32 years, that would be €2,142,616, i.e. just over €2 million. Is that correct? I am aware that the stock market is of course not always a guarantee of clear returns, but the calculator takes it into account
