mac – Similar problem with multiple volumes and missing space

enter the description of the image hereI recently bought a MacBook Pro. I have tried to install Windows using BootCamp without success. When attempting to delete the partition, it seems that I have created more, including "volumes" and that results in a missing space. My goal is the same. To restore the disk to its original size and delete partitions and volumes. I've read the discussions on this side and tried some of the suggested remedies and methods using Terminal without success. I hope you can help me too. I will attach pictures of what the system looks like.
Thank you!!
