When designing a flow, how do you reference data from a record, in that flow?

There is no "table icon" in Flow Designer that you drag onto the flow definition to reference data from a record.

The condition builder is used to define criteria for actions or flows, not to reference specific data values from a record as input for an action.

Data pills are available in the Data panel, not a "data pill related list," and data is referenced by dragging the pill, not just specifying a source table.

In Flow Designer, data from records (such as the trigger record or records looked up by actions) is represented by "data pills" located in the Data panel. To reference specific fields or values from these records within subsequent actions or conditions in the flow, you simply drag the appropriate data pill onto the desired input field or condition builder.

A slush bucket is a control for selecting multiple items from a list and is not used for referencing individual data elements from a record within a flow.
