Like I kinda touched upon in my previous reply, the software isn't the most important thing. It's your understanding of the profession you're going to do. An animator should know what makes a good animation no matter what tools. You can always learn new software. It's not the program that makes a good animation, it's the artist. Life drawing can be very helpful for modelers and animators as it really trains your eye to understand how a human body can pose it self and create interesting shapes with a body. Especially since you're this young I would very, very much try to open your eyes more to the classical side of things. You might think you want to animate or model now, but in six months you might figure out that you love to do textures instead of modelling. Rigging instead of animation. And all the classic art knowledge that you will have will help you no matter which path you choose. It's just something that I see a lot of in new people, too much focus on programs and not enough focus on actually creating art. The program is just a tool. And such some programs will make your work easier, but it will still be you making the work. Okay, mini-rant over. 
Maya is the industry leading program in a lot of creative fields now. Especially VFX. It's getting more traction in games as well after they start to get more and more cinematic. Maya has some very solid animation tools and is getting a lot better on modelling. Just with the last couple of releases it has improved significantly.
So to answer your questions:
-So what softwares should i learn for Lead animator for like games
Maya.
-What softwares or what should i learn for modelling supervisor
Here you usually go for two programs. One for high-resolution sculpting(ZBrush or Mudbox) and one for making the base meshes etc(3DS Max, Maya)
Maya and Mudbox play well together since they are from the same company(Autodesk) and have very similar navigation style as well. And both are quite easy to get into.
-my other questions are is there any private mentoring instead of courses?
There are several websites that provide this, but I would not recommend this at all right now. Find out what you want to do first. Then specialize. Try everything. Don't focus on animation and modelling now. Trust me. Try everything, at least just to know kinda what it is. This will also help you in your career to be able to communicate better with your fellow artists.
You've got websites like Puppeteer Lounge that does modelling and animation mentoring. Again, I would NOT do this until you have found a path that you really like. Do the free tutorials and stuff you can now. Figure out something that you like and that you're good at!
Hopefully I managed to sneak in some more helpful stuff there. Let us know if you still have any questions 🙂
