Can the other person still see the message I delete on my phone

No.

Once sent, a message sent with the Messages app is gone from your control.

You cannot delete a message sent elsewhere.

That ability would quickly become a spectacular means of harassing folks, too.

So... now that we’ve all told you “no” several times, why are you asking this particular question?

No, when the message is sent, it is out of your control.

• You don't owned the message you sent anymore
• You can only delete from your own devices.

No.

And even if it did delete, they could well have screen-shotted the message.
