The meaning of that phrase is “don’t assume things without evidence”. We have plentiful evidence that life should be common in the Universe - of which not the least reason is that the Universe is believed to be infinite, meaning there are countless galaxies out there nearly exactly like out own, with planets exactly like our own.

No serious astrophysicist is claiming there is no extraterrestrial life. We haven’t found any definitive evidence yet, but that’s just because our sample so far has been tiny.

Nobody claimed there was no extraterrestrial life. Most expect some life with at least some algae. Just chances for intelligent life, as more data comes in, turns out to be rather small and with a reasonable chance we’re the only one in this galaxy. The values originally used in the Drake equation were very optimistic.
