One of the top complaints I get from amateur photographers is that their images have come out blurry. The simple answer to this problem usually is that there isn’t enough light reaching the sensor so the camera struggles to take a sharp image.
You can help this by doing a few things - using a tripod (a must in low light conditions!), choosing a higher ISO setting, using flash to freeze any movement or you can avoid using the zoom which makes blurring worse.
Try going through that list and seeing if it helps!
