Credit Card Discussion

ok I got credit card from citibank in newyork. i’m us citizen.
I have never used a credit card. so please understand my trivial questions.
1. continuing from the above question, will my credit card work on any atm machines in the states? as long as the machine says mastercard?
2. Can I use any mastercard atm machine [...]

I know you have to pay to get one, but it only costs around $9. I’m just wondering, do I have to pay monthly payments to keep the visa card? If I use any atm machine, will it charge the fee?
I just wanna know more about it.
