If it were not true then that would be the actual surprise. The probability for life to form has been computed over and over during the past century, incorporating ever more gains in scientific knowledge, and it is on the order of 10-100, meaning that there likely is no other life in at least our galaxy.
There’s no one that can make the estimate accurately right now. Any calculation like that is going to rest on lots on many wild estimates and unknowns. Happy to look at it if you have a source though.
