When using Mac Mail I notice that there is a mailbox called "On My Mac" and a mailbox called iCloud.
I m guessing that OnMyMac means mail is stored on my Mac.
And I am guessing that iCloud mailbox means that the mail is stored in the cloud so my other Apple devices can access mail.
Assuming I am correct Do I need both mailboxes?
Your assumption is correct.
I don't think you can delete either section, and you really shouldn't try.
On My Mac is useful for when you want to archive old e-mails locally. For example, I don't want to keep e-mail since 1998 in iCloud. Most of them pre-date iCloud anyway. So I keep these in "On My Mac" mailboxes, organized by year. I can easily export them to MBOX files and re-import then when I get a new computer.
Note that when I said "archive" above, I'm referring to the general usage of saving documents for posterity. I have no idea with the official "Archive" mailbox and feature in Apple Mail is supposed to do. I never use that.
