Why are single older men who have never been in a relationship before more sad and bitter than single men who had relationships before but single now?

I just found another man on quora who is 55 year old and never been in a relationship before. In his answers he says how he has never been on a real date before, never even kissed a woman and has 0 relationship experiences and how that makes him feel miserable and bitter. He keeps saying how he feels like a loser and how everyone is better than him and how he will be alone forever. Similarly on reddit too I saw 2 men in their 40s who never had a girlfriend before and they too feel terrible and call themselves a loser. These answers scare me as I am 22 and in the same boat as them and never even been kissed. Btw why do these older men who never been in relationship or date feel more miserable, bitter and sad compared to the single men who had relationships before or were married but are single now due to divorce or breakup? I see the divorced men who are single now are not as sad as these men with 0 relationship experiences. Why is it that way?

They feel sad because of missing out on the experience of a loving relation with a woman that the others have had. They have kissed a woman, had intimacy, even if the relationship ended. It makes the former feel like losers. Maybe there is more to it, shyness, feeling uncomfortable in social situations, and so they never had the opportunity to meet someone. Just my estimate.
