[D] XGBoost Always gets 100% accuracy

I have a binary classification problem using BigQuery ML, I did it once with Logistic Regression and got 87% accuracy, then did it again with XGBoost Boosted Trees and got 100%. Is this normal? or am I missing something? I even tried it on another dataset and got a loss of 0.00017 so nearly 100%.
