Seeking Guidance About the Supplication of the Oppressed - Need Clarification, As-salamu alaykum

As-salamu alaykum. I need some clarity about the hadith: “Beware the supplication of the oppressed, for there is no barrier between it and Allah.” I'm thinking about bullying I experienced in high school. Bullies often aren't taught empathy. People who are quieter, more emotional, introverted, or just different tend to stand out and get blamed for not fitting in with those who are more outwardly confident. I remember having an argument with someone in my class who was basically my opposite - confident, socially fluent, and felt they had the right to tell me to just adapt. In that argument I was trying to ask for very little: that people at least try, in the moment, to make a bully uncomfortable because of their behavior - not to “fix” them completely, just to not let them get away with hurting someone. Instead the response I kept getting was “it is what it is,” or “you have to adapt; nobody cared for me and I figured it out myself.” I tried to explain that we aren't the same, and I might be neurodivergent, but the reply was still along the lines of “they figure it out too, in their own way.” When I pointed out that constant blaming and exclusion cause trauma and self-blame, the answer stayed the same: “it is what it is, you can't do anything about it.” I know I’m not imagining this - it hurt, and it felt unjust. I want to understand: am I right to feel that those people should be taught to be more empathetic and open-minded? How, in a practical and spiritual sense, will Allah address this - will He guide them so they learn compassion, or is it something that remains unresolved in this world? I believe Allah knows all and sees our limitations, but I'm struggling with whether justice and change can come for people who oppress others and refuse to understand. Any thoughts, reflections, or advice from an Islamic perspective would be appreciated. Jazakum Allahu khairan.
