What is the source manga of where these lines were originally

It does look like it's from Kaiji or at least something by the same author. Maybe change 'bait' by 'bet'. Otherwise I got a transcription to help future searches:

Fuck you. I'll kill you, you piece of shit. You suffered loss after loss in your life, and ended up here. Unloved by everyone, mocked, and crawling around indecisively at the bottom of the board.

However, there a way out of this cauldron, so your sole priority now is to bait, to bait and get out of here.

Get that through your head. Bait! Baiting is everything! If you don't bait, you're nothing but trash!

'cauldron' is very specific.

I can easily answer all of your questions.
But what would you like do differently if you knew what would happen if you lose?
If that's what want to know, I'll tell you everything.
But there's no way for any of you to confirm if I tell you the truth.
Do you still want to know?
All of you suffered loss after loss in your lives, and ended up here.
Unloved by everyone, inpoverished...and crawling around indecisively at the bottom of society.
Forget the details of what will happen if you lose once more.
Why can't you realize that you're already in the depths of the cauldron of hell right now?
However, there is a way out.
About half of you will be pulled out of this cauldron...so your sole priority now is to win.
To win and get out of here!
Get that through your heads!
Win! Winning is everything!
If you don't win, you're nothing but trash!
If you don't win...! If you don't win...! If you don't win...!

After his declaration, Tonegawa stepped off the podium.
And so... The gamble has begun!

Shut up.
黙れ
I'll kill you, you pieces of shit.
ぶち殺すぞゴミが
All of you suffered loss after loss in your lives, and ended up here.
お前らは娑婆での戦いに負けに負け今ここにいる
Unloved by everyone, impoverished...
誰からも愛される事もなく貧窮しウジウジと...
...and crawling around indecisively at the bottom of society.
...人生の底辺を這って這って這いまわってるのだ
Forget the details of what will happen if you lose once more.
負けて行き着く先が地獄云々よりも
Why can't you realize that you're already in the depths of the cauldron of hell right now?
今ここが既に地獄の釜の底だという事がまだわからんのか?
...so your sole priority now is to win.
...お前らが今なすべき事は勝つ事
To win and get out of here!
勝ってここから抜け出る事!
Get that through your heads!
心に刻め!
Win! Winning is everything!
勝つ事!勝つ事がすべてだと!
If you don't win, you're nothing but trash!
勝たなければゴミ!
If you don't win...!If you don't win...!If you don't win...!
勝たなければ...!勝たなければ...!勝たなければ...!

It's a gamble that you should face as if your life depended on it.
死をも覚悟して望むべきギャンブルや
It's not something you can do based on luck alone.
