Hands are not as complex as you make them out to be in your head. They are rather simple once you learn the form and rules of them. They become easier as you draw them down the line. Fingers have 3 joints and and small indents/bumps that really make it look correct. It is important to keep an eye out for small details.
Some Notes: So generally you want to get basic shapes if you are struggling drawings hands, the goal is to really get the idea of the position, angle, and pose of the hand before adding all the detail. You can approach all the detail if that works for you as well. You should not avoid drawings hands, draw them every single time you can so that way they won't be hard part of drawing eventually. If you wanna master hands learn to foreshortening methods and also just how to show the form of the hands. You can simplify the wrinkles but joint wrinkles might not be best to get rid of since they make it easier to draw hands and fingers. Pay attention to the wrist area connecting the hand.
