Answer 1

Your join syntax is incorrect: https://laravel.com/docs/7.x/queries#joins

Answer 2

Also Your Where condition is Not proper

Answer 3

Problem 1:
Change the multiple condition join method
->join('poll_winner', 'poll_winner.poll_id = poll.id AND poll_winner.user_id = users.id', 'left')
to
->leftjoin('poll_winner', function($join) {
$join->on('poll_winner.poll_id', '=', 'poll.id')
->whereColumn('poll_winner.user_id', 'users.id');
})
Problem 2:
you have two where condition, the where need to be like this, the one is the column, the other be the column's value:
->where('users.id', $user_id)
Problem 3:
If you want to use one string as parameter of select method, you need to use selecRaw
->selectRaw('poll_winner.id AS winner_id, poll_winner.winning_amount AS won_amount,, poll_winner.tax_amount AS won_tax_amount, player_bet.id as bet_id, ...')
Or you need to use multiple strings as parameters of select method:
->select('poll_winner.id AS winner_id', 'poll_winner.winning_amount AS won_amount', ...)
