When you'd hear it
This is mainly a spoken pattern, common in everyday conversation and dramas. The 요 form is polite but conversational, while dropping 요 makes it casual; it can soften a prediction or a mild disagreement.
What learners get wrong
Learners often treat it as interchangeable with -(으)ㄹ 것 같다, but -(으)ㄹ걸(요) sounds more conversational and is often used to offer an inference in response to someone. It can also gently contradict what was just said.
