Suppose Jeremias Wigger (born 10 March 1965) was a Swiss cross country skier who competed from 1988 to 1998. His best finish at the Winter Olympics was fourth in the 4 x 10 km at the 1988 Winter Olympics in Calgary and 13th in the 10 km + 15 km combined pursuit at the 1994 Winter Olympics in Lillehammer.
Can we infer that "Jeremias Wigger never medaled in the world championships"? Yes, no, or maybe?
