The only thing you're right about here is that Spanish is "nearly phonetic" by which you mean that the writing system is orthographically transparent and very standardized. That's true and a huge benefit for learners.

The rest is not right, the word counts in particular is just a reflection of why counting words in a language is hard:

93k comes from the number headwords listed in the core RAE dictionary. The RAE's dictionary of Americanism adds another 70k entries. When you include historical and technical terminology, more comprehensive dictionaries will have well over 300k words.

Counting "over a million" from English comes from way, way more inclusive counting methods that throw in technical jargon, acronyms, global slang, etc. The OED, which would compare to the RAE dictionary numbers, lists only 171k words.

Beyond this, counting is complicated by the fact that compounding and morphological changes work differently, English will use different words in cases where Spanish would use suffixes, and will count compounds as words that in Spanish would be phrases.

"there's only a few ways to express yourself in Spanish compared to other languages." is very wrong. Spanish word order is massively more flexible than English, grammar and morphology more nuanced, they do things in different ways but this is a deep misunderstanding.
