Can anybody help me with this text?

他妈妈靠捡破烂儿供他上完了大学

Below some definitions that I found
靠 kào depend upon; lean on; near; by; against; to support
捡 jiǎn pick up; collect; gather
破烂 pò làn ragged
供 gōng offer (information etc.); supply

Thank you very much

What help do you want (it's not very clear)? Is it that you'd like to know what this sentence means?

Basically, it means, "his mother depended upon picking through garbage (for income) to put him through post-secondary education". This is presumably picking through garbage and junk to find recyclable or reusable materials to resell.

他妈妈靠捡破烂儿供他上完了大学
His mother took him finishing college by the money from gathering rubbish and selling.
do you understand now?
