No. The CSAM (Child Sexual Abuse Material) scanning is comparing hashes of photos about to be uploaded to iCloud against a specific set of images at NCMEC (National Center for Missing and Exploited Children) which are specific to missing and exploited children. It is not machine learning models looking for nudes or similar. It is not a generalized screening. If enough matched images are found, the images are flagged for manual verification. If the manual verification confirms that the images match specific images in the NCMEC database, law enforcement is informed.

Be aware that almost all cloud providers screen photos. Facebook reported 20 million images in 2020, Google reported half a million. Dropbox, Box, and many, many others report images. See https://www.missingkids.org/content/dam/missingkids/gethelp/... to see a complete list of companies that screen and report images.

The other thing Apple announced which is completely separate from the CSAM photo scanning is additional parental controls for the Messages app. If a parent opts in for their under-13 children, a machine learning model will look for inappropriate material and warn the child prior to showing the image. The child is also told that their parent will be flagged if the child looks at it anyway. For 13-18 year olds whose parents opted in, the teen is warned first about the content. If the teen continues past the warning the image is shown and no further action is taken. Parents are not flagged for children 13 and over. As I said, this is a parental control for pre-adult kids. It requires opt-in from the parents and has no law enforcement implications.
