No and Yes. However, with an agency you will earn much more money and need much less time. Without an agency you have to work 24/7, you have to find all trends yourself, you have to create all posts on all platforms yourself, you have no one to help you with the structure and no one with an outside view. And all the other challenges you have to face as well. Many models try to be successful on their own for months, earn only $500-$2000 a month and then switch to us.
