You're not close, either. According to Quora, (don't know how reliable they are but this should be roughly in the ballpark),
According to the latest census data, there are about 7.9 billion people living on our planet as of 2023. That's 7.9 followed by 9 zeros: 7,900,000,000. So if we divide 200 sextillion by 7.9 billion, we get about 25 quintillion stars per human.Oct 2, 2023
Since there can easily be multiple planets per star as well as some without. The existence of extremophiles on earth proves that conditions that would support humans are not necessary for even terrestrial life so thinking a planet has to be earthlike for life to exist is a fallacy.
