Every star is life?
Perhaps, but...
Life is a combination of many thousands, perhaps millions or billions, even trillions, of events and characteristics, which may be impossible to match anywhere else in the universe.
If there is any ‘other’ life out there in the universe, it likely got there through some event that caused some form of life to be shot out into unknown parts of that universe.
And scientists said that there was no life in the bottom of the oceans, no life could survive near volcanic chimneys, etc.
Then again, it could be very possible (given the parameters of time and material) that is a common occurrence. If only one in a million stars produced a life bearing planet, there would still be an almost uncountable number of them in the Universe.
