All people are created by God.
26 Then God said, "Let us make man in our image, in our likeness, and let them rule over the fish of the sea and the birds of the air, over the livestock, over all the earth, [a] and over all the creatures that move along the ground."
27 So God created man in his own image,
in the image of God he created him;
male and female he created them.
Psalm 139 NIV
13 For you created my inmost being;
you knit me together in my mother's womb.
14 I praise you because I am fearfully and wonderfully made;
your works are wonderful,
I know that full well.
15 My frame was not hidden from you
when I was made in the secret place.
When I was woven together in the depths of the earth,
16 your eyes saw my unformed body.
All the days ordained for me
were written in your book
before one of them came to be.
Does God create people who have disabilities? Yes.
Exodus 4 NIV
10 Moses said to the LORD, "O Lord, I have never been eloquent, neither in the past nor since you have spoken to your servant. I am slow of speech and tongue."
11 The LORD said to him, "Who gave man his mouth? Who makes him deaf or mute? Who gives him sight or makes him blind? Is it not I, the LORD ?
12 Now go; I will help you speak and will teach you what to say."
While making life difficult, disabilities in a person's life need not necessarily exempt that person from glorifying God with & thru their lives by demonstrating that God is active in their lives:
John 9: Jesus Heals a Man Born Blind
1 As he went along, he saw a man blind from birth.
2 His disciples asked him, "Rabbi, who sinned, this man or his parents, that he was born blind?"
3 "Neither this man nor his parents sinned," said Jesus, "but this happened so that the work of God might be displayed in his life.
4 As long as it is day, we must do the work of him who sent me. Night is coming, when no one can work.
5 While I am in the world, I am the light of the world."
So even in our suffering with such disabilities, God can still equip us to serve & honor Him. No matter what difficulties we face in life, when we focus on those hardships/disabilities, we sink. But when we make God our focus thru those struggles, we have victory.
