Ran across this term but can’t find a clear definition. Does it just mean to query the blockchain for data, like for example to find the balance of a wallet?

That is the essential idea, yes, but considering the consensus layer, you are not asking a central server, but rather the agreed upon chain by all nodes in the network.
Polling means requesting the latest data (from a full node). Each full node contains a copy of the (Ethereum) blockchain and you can query data from it via a JSON RPC API. Nodes themselves have to sync with each other and keep up to date as well
