Current balance is higher than statement balance—should I pay it off?

Apologies I don’t have a firm grasp on how credit cards work. I actually only use my credit card for utility auto payments as credit card math confuses me. I have a current balance of like $350. My statement balances are always around $160 as the charges on my credit card remains fairly steady overtime. (I did put $800 on it a few months ago for an appliance).

I pay my statement balances automatically every month but why am I carry this higher balance seemingly in perpetuity?
