"Inferiority complex" is an old idea from non-scientific study of psychology.
If you look for recent papers, you'll find that most are either in very low-quality journals, occur as literary or similar analyses rather than real human psychology, or are puns/jokes/references to the concept rather than actually about "inferiority complex" in psychology. For example, this one:
Assimon, M. M., Cutter, G. R., & Bargman, J. M. (2022). The Non-Inferiority Complex: What Do Non-Inferiority Trials Tell Us?. Journal of the American Society of Nephrology, 33(4), 674-676.
A non-inferiority trial is a type of statistical design where instead of testing a null hypothesis that two treatments are not different and declaring a statistically significant result when you observe a difference larger than expected by the null hypothesis, you test a null hypothesis that two treatments are different by at least some margin, and declare a statistically significant result when you observe a difference smaller or in the other direction as expected by chance if the null hypothesis is true. This has nothing to do with "inferiority complex" in psychology, of course, but the author gave the paper a cute name making reference to the old-fashioned idea.
The idea of the inferiority complex goes back to Alfred Adler, a contemporary of Freud. Reading about Jung, Freud, and other similar past figures in the field might be useful to understanding the history of psychology, but just like we don't use Galen or Aristotle in treating modern medical patients, I'd highly recommend against using Jung or Freud to understand actual psychology.
I observed that some people try to show that they are more powerful and always wants attention in group of people and for that purpose they humiliate others and make them feel incomplete means they knowingly & unknowingly makes other person also inferior.
It sounds like you are describing bullying behavior. There are lots of explanations for bullying, but generally the attempts to scientifically link perpetration of bullying to low-self esteem are mixed or show very modest associations, for example:
Tsaousis, I. (2016). The relationship of self-esteem to bullying perpetration and peer victimization among schoolchildren and adolescents: A meta-analytic review. Aggression and violent behavior, 31, 186-199.
