It depends on the specific tutorial you are watching. Some AI tutorials may assume a certain level of prior knowledge or experience, while others may be designed for beginners with no prior background in AI. It is better to go with basic level tutorial and then move to advanced tutorial. For such I would like you to watch this below tutorial by Intellipaat which doesn't require any pre requirements anyone can watch it. As all the concepts from basic to advanced are covered in an organized manner along with hands-on labs which helps in better understanding of concepts.
