Is it certain that more cash on the cash flow statement means that there is more revenue on the income statement (and vice versa)?

What will be an ideal response?

No, more cash does not necessarily mean more revenue. An income statement will be similar to a cash flow statement except that it records those times when a company earns "revenue" without immediately receiving cash for it (such as when the business was owed money but have not received it yet), and when the company incurs "expenses" but don't have to pay cash immediately for them (such as when something is bought on a credit card or an account). It is possible for an organization to have little or no cash but still be profitable (or vice versa).
