Do I need to pay tax?

Hi all, I'm new to this sub.

I'm 22 M. Working in IT, with decent salary of 6.5 LPA. In hand is approx 50k per month. I'm literally confused about my taxation.

I've watched various YouTube videos and I'm not getting those. Could you guys help me in understanding it. Or could you share me some related post where I can easily understand. Thanks.
