No, but it helps. An architect doesn't need to be good at drawing in order to be a great architect, but it certainly does help. Being able to visualize and communicate your ideas through sketches and diagrams is extremely important, especially when working with clients and other stakeholders who might not be familiar with the architectural design process. That said, there are plenty of successful architects who aren't particularly good at drawing (or don't enjoy it), and there are also many software programs out there that can help you create professional-looking renderings without having to put pen to paper.

This is a difficult question to answer. Some architects may feel that they need to be good at drawing in order to be successful, while others may not feel that this is necessary. Ultimately, it depends on the individual and what they want to achieve with their career. That said, being able to draw well can be a valuable skill for an architect. It can help them communicate their ideas more effectively and make it easier for them to see how certain designs will look once they are implemented. However, there are many other ways for architects to create or communicate their designs, so it is not essential for them to be good at drawing.
