Tolerance for drinking in different countries

I’m just curious since often times I see people on tik tok implying that 3 shots of vodka is enough to get really drunk. Some say that it’s their limit. Sometimes dudes who are bigger than me.

And I find it strange since I never saw someone getting drunk off 3 shots of vodka. Even better I never saw someone get drunk off 3 shots of moonshine.

So I’m wondering what the actual tolerance is for most people in other countries. I’m from poland and there’s obviously this joke going around that slavs have highier tolerance for drinking. But I struggle to believe that’s true. Me personally I have low tolerance, but I can handle like 10 shots maybe not back to back but throught like 2 hours I can drink 10 shots 40%vodka and be reasonably drunk. And I’m not even a big drinker I drink maybe 2-4 times a year. I remember when I was drinking for the first time at 17 I drunk like 15 shots throughout the night and was fine.
