It does, it just depends on how it’s coded. Like, take word order. If you have a case system with nominative, accusative, etc. your word order can be pretty free, you can move objects to the front of the sentence like ‘food-ACC eat I-NOM’.

Remove the case system and it’s simpler to encode the words, but word order becomes much more fixed.

All languages are equally complex, in theory at least, but where the complexity lies is different.
