K-fold cross-validation trains k different models, each being tested on the observations not used in the learning procedure , as you are not using the same model as in your reference case, neither the same test set The approaches that you describe are different, although I would not recommend the cross-validation only
Exceptionally high accuracy with Random Forest, is it possible? Here is an example of how you can perform cross-validation in python using scikit-learn In addition to accuracy I would also try to calculate and compare other validation metrics in order to get a more complete picture about the model's performance (e g precision, recall or more concise ones as F-score)

Large negative R2 or accuracy scores for random forest with . . . The solution is simple Shuffle the original dataframe before splitting into X, y for cross-validation df = df sample(frac=1, random_state=0) This solved my problem, now the test and train scores from GridSearchCV are both between 0-1, comparable to a simple train_test_split
