no, some were just plain fishermen and one was a tax collecter. None of His disciples were even close to weathy in terms of money.
"Wealth" is relative.
The original twelve were all gainfully employed and had jobs that supported them... some perhaps better than others. Even Judas "had the bag" (was the treasurer of the group - John 13:29).
There was only one who was said to be "rich":
"...there came a rich man of Arimathaea, named Joseph, who also himself was Jesus' disciple..." (Matt.27:57). But he wasn't of the twelve.
Jesus is recorded to have had a second home in Capernaum, besides the one in Nazareth, whereby, being the firstborn of His "legal" father, Joseph when he died, He became the head of His family's household... and CEO of His father's family-owned "construction business."
In those days, Capernaum sported the homes of many wealthy and influential people. Hot springs, spas and indoor baths and plumbing were part of living in Capernaum in those days. The upper-crust lived there... doctors, lawyers... and an occupying Roman Centurion lived there.
"...when Jesus was entered into Capernaum, there came unto Him a centurion..." (Matt.8:5)... who displayed a remarkable faith of which Jesus marvelled.
Peter also had a home in Capernaum, which his family's fishing business financed for him. Following the centurion incident, Jesus made His way to Peter's house:
"...when Jesus was come into Peter's house, He saw his wife's mother laid, and sick of fever..." (Matt.8:14).
While they aren't said to be "rich" in God's Word... Jesus and Peter, at least, are recorded to have been "wealthy" enough to own homes in a very "wealthy" neighborhood.
They were certainly not the "poor homeless street beggars" that some people make them out to be.
"...they went into Capernaum; and straightway on the Sabbath day He entered into the synagogue, and taught... and forthwith, when they were come out of the synagogue, they entered into the house of Simon (Peter) and Andrew, with James and John..." (Mark 1:21-29).
"... again He entered into Capernaum, after some days; and it was noised about that He was in the house (at home)..." (Mark 2:1).
