The accuracy of a random forest algorithm is nearly 1, how do I solve this problem? (with updates)
To answer your questions: increasing the max depth of a Random Forest algorithm may increase complexity. Even though your 91% accuracy for the code you listed is test accuracy, this still could mean ...

I guess the question is whether this is too good to be true, and if so what could be leading to it.
Domain knowledge is the first suggestion: if you know others have modeled this or similar problems, ...

SVC labels entire sample majority class, even after using ADASYN
To answer your first question, you could try different resampling techniques (random oversampling, SMOTE-ENN, etc.) to see if that would help. Though this may not be the answer you want to hear, SVM ...

Machine Learning Binary Classification Model on a Small Tabular Imbalanced Dataset - Improving Performance
I don't think PCA will be particularly helpful in your case since you only have 10 features, unless your one-hot encoding is creating hundreds of additional features or the 10 features themselves are ...
