Is it true the irish and scottish are the best fighters?

i read a source about how the irish and scottish are known for being some of the best fighters among all men and women around the world their culture is based around fun and fighting so i could see why also I have noticed the irish and scottish men are usually bigger than most men in broadness and height is there any connection also i watched a scottish man beat a bloods ass on the street in chicago the blood was talking about gang shit and he got in the scottish mans face the scottish man was about 6’2 and had a muscular build also very white like damn near albino 😂 the blood was 6’1 if day and also fairly muscular he also was extremely dark it was like watching him and yang in a fist fight 💀 i watched the blood get beaten badly he swung but the scottish man just dipped it and hit him with a counter that laid him flat he got back up and hit the scottish man but he didn’t look very dazed at all and he hit him again and that’s when he hit the ground and didn’t get back up i saw that and that’s when i was curious does nationality and fighting skill have any connection
