Since between 1500 and 1650 some 450.000 Spanish migrate to America from a population of around 7 to 8 million, and the migration begun with Columbus 2nd voyage in 1493, that sentence doesn’t seem true, but a perpetuation of a myth.Spain's colonies were more of conquered provinces to rule and exploit and less of locations to transplant people.
How many English, French or Dutch migrated to America in the same time period?
There is a study at JSTOR that you can have a look:
