CMV: English has less dialects, regionality, and accents which makes it easier for people learning it as a second language compared to visa versa

Spanish is my second language and from my experience there are tons of differences between Spanish between countries as well as dialects. For example: I’m listening to Alvero Soler(Spain) and he says cojitos a la mano in a song. Which means grabbed by the hand, but I learned Spanish in South America and it doesn’t mean that. It’s anecdotal but wondering gif people have data/logic that could prove me wrong. Yes I know that there are regional differences in English too, but I don’t know it’s to the same level as multiple countries have regional differences. Also I feel like many Latin countries have many indigenous languages that get mixed with Spanish that English doesn’t get as often.
