I grew up in a very male-as-default English-speaking culture. Any animal, robot, or plant would be referred to as it or he, unless that creature/thing has additional female markers such as wearing pink, makeup, etc.

For examples look at the designs of Mickey and Minnie Mouse or Babs and Buster Bunny. If you draw a little blob with eyes, people will say "He's/It's cute." If you put a pink bow on it, they will say "She's cute."

You can even look at the word "woman" itself. "Man" originally just meant any person, but "woman" was invented to speak specifically about a "wife-man." Going to your German examples, why did they make special words for female bakers, etc. and none for male bakers? It's because male is the default and female is a deviation from that norm. You don't need a special word to describe the default assumption.

There's this old riddle:

A father and son are in a car accident. The father dies at the scene, and the son is rushed to the hospital. When he is taken into the operating room, the surgeon says, "I can't operate on this boy! He's my son!" How is this possible?

It plays on one's assumptions about gender.
