I recently found out about this song that was used during the Irish Civil War by the IRA that dates back to the 18th century, called Óró sé do bheatha abhaile. However, while listening, I heard quite a resemblance to Yankee Doodle Dandy. I showed some people and they disagreed, so I'm turning to online sources. Is it the same tune as Yankee Doodle Dandy? I will add links for both songs. I will greatly appreciate if someone can verify if it is the same tune or not.

They are not the same tune. You can compare the sheet music of Yankee Doodle and Óró sé do bheatha 'bhaile. I'm guessing the similarity you're hearing is in the final line of the refrains of each song. There is a pretty similar progression of notes in that final line. When you compare and with the girls be handy to anois ar theacht an tsamhraidh, there are some similar intervals. In particular, the last three notes involve a minor 7th then the repetition of a note. However, the interval progression is not exactly the same in the rest of the line.
and with the girls be handy = EDGF#AGG = minor 7th, perfect 5th, major 7th, minor 3rd, minor 7th, unison
anois ar theacht an tsamhraidh = GAEGEDD = major 2nd, perfect 5th, minor 3rd, major 6th, minor 7th, unison
You're picking up on how the perfect 5th, minor 7th, and unison are in the same spots. In addition to that, some of the intervals are inverses of each other, like the minor 7th and the major 2nd in the first interval.
It has been speculated that the tune for Yankee Doodle comes from a different Irish tune, "All the Way to Galway", although the song itself is Dutch in origin and may come from a Dutch tune as old as the 15th century.
