I need to identify the categorical columns and count their distinct values. Let me start by examining the column metadata to understand which columns are categorical. ```json { "action": "tool_call", "reasoning": "I need to identify all categorical columns across both tables and get their distinct counts. The dataset card shows classifiers like Rank, Assoc, Gender, and Name. I'll inspect both tables to get complete metadata including distinct counts for all columns.", "tool": "inspect_columns", "args": { "table": "ittf_rankings" } } ```
