US just has a massive podcast culture. All of my US friends listen to podcasts in some way, even if it's just when flying.
Meanwhile it would be news to me if any of my friends in Mexico and Spain (the two places I spend time in nowadays) listen to podcasts at all. I also listen to Mexican/Spanish podcasts to practice the language, and there just is no contest with the top 1% of US podcast -- what most people are listening to. So you need to also have a sufficient proficiency in English to get into podcasts.
The sibling comment focusing on public RSS feed is looking down the wrong rabbit hole when there's a simpler answer: US has high absolute and per capita numbers for podcast listeners which is what you need to have a culture of podcast production.
