Why each word id from tokenizer distilbert got different even it's the same word ex: "Sebab:2953" & "Sebab:1061"?

I’was try to print out the id from tokenizer which char gonna print out then when I was code it but I only can print out the sentence but for each same word had the different id token, how to make the same word in one ID tokenize? Sorry for bad english grammar…

Source Code:

model_class, tokenizer_class, pretrained_weights = (ppb.DistilBertModel, ppb.PreTrainedTokenizerFast, 'distilbert-base-uncased')

tokenizer = tokenizer_class.from_pretrained(pretrained_weights)
model = model_class.from_pretrained(pretrained_weights)

tokenized = x.apply((lambda x: tokenizer.encode(x, return_offsets_mapping=True, add_special_tokens=True, max_length=50, truncation=True)))
print(tokenized)
