Default $args is ‘hide_empty’ which can be ‘hide_empty=true’ or array(‘hide_empty’ => true).

function wp_count_terms( $args = array(), $deprecated = '' ) {
	$use_legacy_args = false;

	// Check whether function is used with legacy signature: `$taxonomy` and `$args`.
	if ( $args
		&& ( is_string( $args ) && taxonomy_exists( $args )
			|| is_array( $args ) && wp_is_numeric_array( $args ) )
	) {
		$use_legacy_args = true;
	}

	$defaults = array( 'hide_empty' => false );

	if ( $use_legacy_args ) {
		$defaults['taxonomy'] = $args;
		$args                 = $deprecated;
	}

	$args = wp_parse_args( $args, $defaults );

	// Backward compatibility.
	if ( isset( $args['ignore_empty'] ) ) {
		$args['hide_empty'] = $args['ignore_empty'];
		unset( $args['ignore_empty'] );
	}

	$args['fields'] = 'count';

	return get_terms( $args );
