Help Needed As A 19 y/o Wanting Financial Freedom

Hello everyone, as the title states, I'm wanting to get into stocks and investing but I have no idea where to start and what to do.

I'm currently working as a freelancer and earning enough to put away 20-30k monthly and in a few months even 100k/month somewhere to set myself up for the future.

My only concern is that whatever I work towards needs to have instant liquidity and very low risk. I've heard Meezans Mutual Funds are a good option.

Apologies if I sound shameless asking for a blueprint /steps to follow at the cost of someone's years of knowledge. I just want to be financially secure 10-15 years from now or even more. If someone could guide me what apps to use to reduce deductions as much as possible and where to go from there I would really appreciate that
