How did the episode of Champaran change the plight of the peasants?

The peasants' morale was boosted after receiving reimbursements from the Britishers; they now knew they had rights and protectors.

They were able to get coverage in order to fight for their rights.

Later, Gandhi established schools in six areas, where Kasturbai taught ashram principles on personal hygiene and societal sanitation.

Hence, the peasants got their rights and courage by the Champaran episode.
