Some cravings are rooted in simple nutritional deficiencies as the body tries to get what it needs. For example, sometimes you crave salt but what you really need is water because you're dehydrated (via Healthline). The body gets you to consume salty food so you'll drink and replenish fluids. It's an inborn protection system.
However, when it comes to citrus fruits, there is no medical science behind why some women seem to crave oranges, grapefruits, and other citrusy flavors when pregnant and some don't. Cravings are very individual.
According to Verywell Family, fruit is one of the more common pregnancy cravings, though. The bold, bright flavor may be one reason since women naturally want stronger flavors when pregnant. During pregnancy, you also have changing nutritional needs and sensory perceptions due to an influx of hormones, which can add to your desire to consume more citrus fruits and drinks.
