Hello OP - my job involves working with statistics and modelling, so I can hope I can help in a small way.
We know that the vast majority of humans find it difficult to comprehend risk at a population level (it's not any kind of failing, it's just that our brains really aren't wired to work that way!).
So, to put things in perspective:
Your chances of dying in a road accident in the UK are about 1 in 20,000 (assuming you attain an average lifespan, that's a lifetime risk of about 1 in 240).
(That's actually very low, thanks to the UK's laws on road safety, car maintenance etc - you should some other countries' stats...)
However, most people continue to drive / cross the road etc on a daily basis.
So, given that the likelihood of the occurrence of a clot as a result of the AZ vaccine (and I believe that stat refers to occurrence, rather than deaths - obviously I'm not an HCP, but I believe that most clots can be treated successfully and few lead to death) is around 1 in 50,000 - more than double that of a fatal RTA - the risk is very, very low indeed and much lower than getting in a car.
As I say, I work with data a lot and if I'm getting overwhelmed by messages, I find statistical analysis weirdly comforting. I hope I've been able to help you a little.
