ACF stores a list of user IDs as a serialized array.

The meta key of the field will be "{$group_field_name}_{$sub_field_name}"

your meta query might look something like this

'meta_query' => array(
  array(
    'key' => "{$group_field_name}_{$sub_field_name}",
    'value => '"'.$user_id.'"',
    'compare' => 'LIKE'
  }
)
