About twenty years ago, I was taking a flight back from Rio de Janeiro, Brazil to the US. In the middle of the night the pilot got on the loudspeaker and said "hi! Having some engine trouble, so we are landing in Manaus." Manaus is in the middle of the Amazon. Needless to say, a bit scary to hear that, but we landed without issue. They told us we had two choices: the nice hotel with a shared room, or the lesser nice…
1) +95% of the population live on the coast very far away from the Amazon. Most of the population has not been there. Most of the coast has a very different jungle biome called Mata Atlantica and the countryside close to the coast is not that different from temperate forest of Europe. That is what most all Brazilians are used to. There is a significant population in the arid northeast though and the cold south as well (which is even more similar to europe).
2) Manaus is the biggest city in the Amazon and it is huge developed place (and has been for decades). You are not in the middle of the jungle if you land in the airport. The countryside around the city is jungle though.
3) Brazilian people do not necessarily like or are used to tacos and spicy food. Mexico is _really_ far away from Brazil.
