It's estimated that about 1 in 20,000-30,000 eggs has salmonella. The rest are safe to eat raw. So you have a 1 in 20,000-30,000 chance every time you eat an egg of coming into contact with the bacteria, but on top of that there's a good chance your immune system will deal with it and you won't get sick regardless.
The elderly, those with immunodeficiencies, pregnant/breastfeeding women, infants should probably avoid uncooked egg to be on the safe side. If you're a healthy adult then you can probably take your chances, depending on your aversion to risk in general.
