Au contraire - your chances of living a long life are excellent! Your plan for consultation going forward is a good one and will help you decide on the appropriate treatment.
BTW, don’t be too hard on your urologist. He sounds pretty current and was probably very surprised by your Decipher score. Who knows how many patients he saw that day - or before your conversation - who refused treatment or advice? He’s only human and his frustration came boiling to the top. I was in healthcare for many years and often asked my patients in frustration “Why do you even come here if you know more than me?”
That said, he should have recommended further consults and given you more options for treatment. Best,
