And now back to the question of how Samus, a normally-proportioned human, fits into the shoulder and hip parts of the suit
You’re ignoring the real question.
HOW BALL
The ball is over a meter / 3ft across
It’s been like 20 years since I played it, but I seem to remember some logs in Prime referencing the horrific results of Space Pirates trying to replicate the morph ball.
There was actually a really old Super Metroid magazine ad which featured a cutaway view of Samus inside the armor and it showed how she fit inside!
That’s awesome!
I can’t say how logical it is, but lore-wise the suit doesn’t actually frame her body proportionately, it’s larger and her feet only go to the shins and her arms only go halfway down the suits arms. The way it moves without 1:1 mechanical input from her body is assumed to probably be related to the “biological” aspect of the suit inside that is made of living tissue and is essentially an extension of her nervous system.
