HUGS
Because it is a very invasive operation it is somewhat more risky than less invasive surgery. As said, it depends very much on the vet and nursing team.
However, if the womb has started to go wrong in addition to the ovarian cysts, without the operation your girl would have a massively reduced life expectancy. It is one of these 'between and rock and a hard place' choices. You can buy your girl several more years of life with a certain risk against weeks or at the best months of life for sure.
That is the wider picture in which your vet has made their decision to operate; not because they are looking forward to it. Any failed op is as hard on a vet team as it is on the owner. It is always a weighing up of risks and benefits. In your case, the cance to reap benefits is still greater than the risk.
The examples in this thread will hopefully show you
that it is a survivable operation and that the benefits in terms of an extended life span are considerable. It also perfectly normal to have second thoughts at this stage.

I am very sorry; there is nothing nice about this kind of situation, in which I have found myself often enough over the years. My thoughts are with you as any operation is an anxious time.
