In this sentence, 想 means would like to / want to.
So 我想在柜台补办银行卡 means something like I’d like to reissue my bank card at the counter.
想 can also mean to think, but that is usually clear from context:
- 我想去银行。 = I want / would like to go to the bank.
- 我想这个办法可以。 = I think this method works.
Here, because 想 is followed by an action (在柜台补办银行卡), it is understood as want to / would like to.
Here, 在 means at / in / on, and it introduces the location where the action happens.
- 在柜台 = at the counter
- 在银行 = at the bank
- 在家 = at home
So in this sentence:
- 在柜台补办银行卡 = reissue the bank card at the counter
It is functioning like a location phrase placed before the verb.
