I'd do something like this:

is_header = not any(cell.isdigit() for cell in csv_table[0])

Given a CSV table csv_table, grab the top (zeroth) row. Iterate through the cells and check if they contain any pure digit strings. If so, it's not a header. Negate that with a not in front of the whole expression.

Results:

In [1]: not any(cell.isdigit() for cell in ['2','1'])
Out[1]: False

In [2]: not any(cell.isdigit() for cell in ['2','gravy'])
Out[2]: False

In [3]: not any(cell.isdigit() for cell in ['gravy','gravy'])
Out[3]: True
