Early polls yes. Polls just before the 2016 election showed closer to a 1/3 chance. And the final results were within the margin of error.

But, these are early polls, so, yes, don't put much stock in them, but not because polling is worthless.

May he receive the sympathy he has shown to others.

Hey man, it sounds like you still may be depressed. From one internet stranger to another, I want to tell you that you have value. From your post I can infer that you're an eloquent writer, that you consider the feelings of others, and that you appear to treat other with kindness. We need more people in the world like that. Please, seek out a mental health professional if you feel depressed or suicidal.

I was depressed for while in my 20s. I was stuck in a job I hated, living 1000s of miles from my family, lonely, and zero prospects for a relationship. I spent all my free time alone and distracting myself from my depression with video games. My worldview was devastated as I had been learning that I was raised in a cult. I was unnecessarily carrying shame from my childhood for normal human behavior. Also, I was still a virgin* until 30. (*Now I think the term "virgin" is a weird harmful patriarchy concept. A person's value is not indicated by whether they have had sex or not.)

Although you're a bit older now than I was at the time, we are about the same age now. We are not too old for happiness. Things can and will get better. The night after I married my wife (mid 30s), I broke down sobbing because until that moment I wasn't sure anybody would fully accept me as I was. But she does, faults and all, and goddammit I love her for it.

Tell us your story. Why do you think you haven't ever been in a serious relationship?
