Based on hundreds of sources, the risk for Long Covid hovers around 10 percent for both adults and children. That's the number given by an important study "The Immunology of Long Covid" in Nature Reviews Immunology. Conditions range from "breathlessness and neurocognitive impairment" to "increased risk of stroke, myocardial infarction, and types 1 and 2 diabetes." As the authors put it, "the oncoming burden of long Covid...is so large as to be unfathomable."

Another study in Medical Review puts the risk for Long Covid even higher, at 10-30 percent for a single mild infection. According to this study, that number doesn't include the organ damage caused by mild and asymptomatic infections. Once you take all the research into account, your risk rises to somewhere between 50 and 70 percent. As the authors state, "well over 50 percent of people...who have contracted Sars-Cov-2 suffer damage to their organs." That's worth repeating:

More than 50 percent.
