No. You can't.
You can't "clone the OS" over from an Intel-based Mac to an m1 Mac (any kind of m-series).
What you CAN do:
- use CCC to create a cloned backup of the 2019 iMac
- take the new Mini out of the box, get it set up on the table. DO NOT press the power on button yet.
- update the CCC clone so that it's "the latest".
- connect the cloned backup to the new Mini.
- NOW press the power-on button on the Mini for the first time.
- begin setup. setup assistant will ask if you wish to migrate from another drive. YES, you do
- "point the way" for setup assistant so it finds the CCC backup.
- give SA time to "digest everything". It takes a while, be patient.
- SA will present a list of stuff to migrate. I suggest you just migrate everything.
- Again, be patient. When done, you should see your old login screen, just as before.
