You have no way of knowing your personal level of risk beyond the very blindingly obvious.
Your level of risk is exactly the same as those who are taking social distancing seriously. I'm not high risk. I'm not vulnerable. I am as capable as you of catching the virus and unwittingly passing it to others while incubating it, or while being asymptomatic.
Those I unwittingly pass it to may be more vulnerable than me.
Or I could pass it to you.
And even if you are not obviously vulnerable, you may become seriously unwell.
Of course I don't think we are all going to die. What a hysterical thing to suggest. Again, does it make you feel better to imagine I'm inflating the level of risk in my own mind? I'm not.
You however seem to be minimising it. The question you need to ask yourself is why you feel you need to do that. What is frightening you?
There is no good reason for anyone to go within 2 meters of another person in a supermarket. Being hysterical about it when people object is very irrational. This virus has a long incubation period. Social distancing protects those vulnerable to it and so we all need to avoid catching and spreading it to those vulnerable people. It doesn't matter if you and I are not vulnerable. It's still a problem if we spread it between ourselves. Not because we are likely to die, but because we are likely to unwittingly spread it to others who are vulnerable.
Reflect on why you feel the need to minimise the risk. Does it make you feel safer?
I'm in favour of getting everyone back to work asap by the way, with appropriate social distancing measures. Managing the risk sensibly is the way forward.
Dismissing people who take sensible precautions seriously as hysterical or as drama llamas is, ironically, the only histrionic response I'm seeing on this thread.
