It is a whole world of rhythms and feels.
I am still working on it and have been hitting my head many times.
Recently I played with the great Roberto Pla, so I am probably doing something right.
Briefly and approximately (you need to do some research yourself, I don't have sources handy):
"Latin" (including most of the Spanish speaking South American countries but not Argentina) is often based on the clave. There are four of them mainly used. Son and Rumba, 2 3 and 3 2 each (hard to explain with words). Learning to clap hands on the 3-2 and the 2-3 son clave is the first step.
The 2 3 has no downbeat marked.
It feels like it's played on or ahead of the beat.
"Brazilian" is another (huge) world of rhythms. Common styles are samba and bossa.
Not as strict as son or rumba, the downbeat is often marked. On bossa, guitar usually gives a solid meter. On samba the downbeat might be sometimes confusing, but if you try to dance (without overdoing with booty moves) it is easy to get.
"One note samba" is actually a bossa.
It feels like it is played behind the beat.
Listening to the stuff helps; a pleasant and long journey.
