Crudo always begins with something raw, usually fish or shellfish, but sometimes even thinly sliced raw meat. Then Crudo is dressed with an oil and citrus mixture. Sashimi uses raw fish, but usually without a marinade, sauce, or even a garnish. It is sometimes dipped in soy sauce. Ceviche is made with raw seafood that is "cooked" in a citrus juice marinade that cures it. Ceviche calls for more acid compared to Crudo, resulting in a different texture.
