They are not exactly the same as modern Irish but Highland Scots did come from Ireland.
Irish tend to be handsomer, Scots tend to be smarter.
Yes they were. Irish and Pictish.

The Scoti, an Irish tribe, migrated to what is now Scotland. I don’t recall who occupied the territory prior to the arrival of the Scoti.
From Wikipedia: “Scoti or Scotti is a Latin name for the Gaels,[1] first attested in the late 3rd century. At first it referred to all Gaels, whether in Ireland or Britain, but later it came to refer only to Gaels in northern Britain.[1] The kingdom they founded became known as Scotia or Scotland, and eventually all its inhabitants came to be known as Scots.”
“Scotia is a Latin placename derived from Scoti, a Latin name for the Gaels.[1] Originally, it meant the land of the Gaels: Ireland and part of northern Britain. From the 9th century, its meaning gradually shifted, so that it came to mean only the part of Britain lying north of the Firth of Forth: the Kingdom of Alba or Scotland.[1] By the later Middle Ages it had become the fixed Latin term for what in English is called Scotland.”
