the proles
Just as the quote goes "Only the proles are free" and if there's hope, it lies in the proles. Winston knows that the only one that are free from the monitor of the party are the proles. Hence he viewed them as the only hope for freedom. However, the proles are not really concerned about this.

Winston says that hope for a better society lies with the proles (more properly known as the proletarians.) Winston states this because the proles are unobserved by the Party (and therefore are free to think as they please) and because the proles are larger in number than any other group (Outer or Inner Party.) Winston believes that by living the way they have, the proles have succeeded in "staying human."
Winston Smith hopes that the proletarian class will 'awaken' to their oppression and overthrow "Big Brother" but O'Brien assures him that this is an imaginary scenario because the proles are little more than animals .

Hope for rebellion resides in the proles
The Inner Party provided the spectable for the Proles in "1984" because the party members were thought to be taken care of by the government, while the proles were left to their own devices in caring for themselves.

The proles are the only ones that are free in the society in 1984. They are not monitored by the party or telescreen and are free to do whatever they want. Hence Winston see them as the only hope to overthrow the party. However the proles usually just spend their days betting on lottery, drinking etc.
Mitromorpha proles was created in 1922.
Orwell describes the proles in 1984 as being uneducated, impoverished, and politically apathetic because they represent the majority of the population in the novel who are kept ignorant and distracted by the ruling party. By keeping the proles in this state, the party maintains control over them and prevents any potential uprising or rebellion. This serves to emphasize the stark contrast between the oppressed proles and the privileged Inner Party members.
