Cannot delete partition on macOS Catalina

Hi, I somehow partitioned my disk. It's a different story, anyway I deleted some partitions by erasing the part and then clicking the minus sign in Disk Utility.

However, I still have the disk split into 2 parts ("Untitled" where I have my stuff and "Verze 3") and I cannot delete the "Verze 3". I read here that "Since you APFS container is the last entry (disk0s4), there is no way to grow it backwards." But the "Verze 3" is not APFS.

So what can I do know? Can I delete the entire disk and make it just one storage?

My Terminal:

/dev/disk0 (internal, physical):

   #:                       TYPE NAME                    SIZE       IDENTIFIER
