are all visa cards connected with bank accounts?

not necessarily. you can issue credit cards without a bank involved, although companies which do so may have additional legal complications, such as usury regulations. as an example, amex is a network which also issues cards themselves. the company is not a bank; they sold their banking subsidiary in 2007. it's also possible to get a bank-issued credit card without banking with that same company.
