What does Psalm 37:25 mean?

This verse is controversial but can be understood in the broader context of Scripture. David's point here is not that the "righteous" will never experience poverty, hardship, or even death (Psalm 34:19; John 16:33). Rather, his meaning is in the context of recovery (Psalm 37:24).

Strictly speaking, David is referring to his own observations, not necessarily an absolute condition of the entire world. We know that famines have struck nations in which both believers and unbelievers have died from starvation. Poverty and destitute circumstances can affect even those who honor God. Certainly, as a general rule, God provides sufficiently for His people (Matthew 6:31–33). Believers should not worry about what they should eat or drink or wear because their heavenly Father is aware of their need and has promised to meet it. That provision is not always according to what we prefer, or what we expect, but it's always according to God's perfect will (Romans 8:28–30).

The apostle Paul thanked the Philippians for sending help for his needs twice (Philippians 4:16), and he promised, "My God will supply every need of yours according to his riches in glory in Christ Jesus" (Philippians 4:19).
