I mean...yes, this is thoroughly documented throughout all of Judges/Kings/Chronicles/etc. Elijah is the one who stands against 450 prophets of Baal, and when he feels totally alone later on, God tells him that 7,000 haven't bent the knee - big enough to be reassuring, but certainly not a huge percentage of the northern kingdom's population.

Elijah (who, unlike Moses, is probably a real historical figure) lived long after the events depicted in Exodus. And Exodus ends with the all of the Israelites faithfully following Yahweh's commandments, after narrowly avoiding death for their worship of the golden bull idol. The book of Kings presents a time long after that, when the people of the now divided Israel have lost their way and started worshiping Baal - as opposed to their ancestors who only worshiped Yahweh.
