According to Blogger, in the last two hours, I've had 11 visitors from the US, 6 from Argentina and 5 from Italy. In my counter, only 3 visitors from Argentina are showing. Could you help me solve this problem? Thank you in advance!

Different counters lead to different results, I don't think there is any "problem" here. They simply count visitors in different ways

I've read somewhere else that if someone had already visited your blog before you created your Flag Counter and that person visits your blog again, it's not going to count as a visitor

Not true, it will count

I added the html code to the sidebar, so no matter where you click or what post entry you're reading, the counter is always showing. Do I need to add it somewhere else?
The link is turinconargentino.blogspot.com.ar in case you want to check the placement of the counter.

We have no way of knowing who has visited in the past

Oh, alright. I thought it had something to do with Cookies.

I can understand that numbers may vary a little, but what I don't understand is why the counter is showing just one out of the three countries that have visited my blog. The US and Italy, for instance, don't show up.
 

Ah I thought the problem was just for the other country.
If the counter is not on every page (let's say it's just on the HP), maybe they didn't visit it / load it
Or maybe they ended up as unknown country / proxy?
Maybe they're bot visitors that FC don't register?
Maybe they had very bad internet or left befoe the image loaded?
Maybe maybe maybe maybe?
Lots of things could have happened tbh but it's sure that if a person visit ur blog (READ: loads the flagcounter image) it is going to count (nothing can prevent this really)
