Add: when in conversation in real life while learning, most native speakers are fairly patient and will let you finish and try to understand in slower paced countries in South America. If you try to do that in Spain or Miami, it won't happen. If they speak English also, they will switch immediately as they are always in a hurry.
i don't know where in spain you found anyone fluent in english but in my vast experience living in and traveling around much of the country that is NOT the case. i lived in Valencia and Sevilla and it was the BEST thing for my spanish because i could not rely on english to help me at all.
in miami, of course, the level of english is much higher as it is still part of the united states, but i went with my Cuban boyfriend in 2016 for 5 days to dance and we didn't speak english to anyone the entire trip. that being said, i'm sure if we tried, they would have been able to speak it to us, but in many parts of miami, spanish is preferred.
