I know you have a better grasp of statistics than the average bear. Let’s do some quick and dirty calculations with numbers from wikipedia.
There are about 69 billion eggs produced in the US each year. About 2.2 million of them are contaminated with salmonella … so your chances of running into one are around 31,000 to 1.
That would indicate that if you eat a raw egg every day you would get infected once every 82 years. That number is actually too low because most of the contaminated eggs come in clumps, not scattered randomly … if you don’t get sick from the first egg in a carton you can be pretty confident you won’t get sick from the rest of them, either.
You should also factor in that you are not eating the eggs raw. You goal here is to cook them to proper temperature without overcooking them.
I would say you are statistically more likely to come to harm on the drive to the grocery store than from eating a slightly undercooked egg. Drive carefully.
