Anon, I was like you 2 years ago when i was 18. 6", 92 kilos, fat fuck who got exhausted running and couldn't lift for shit.
I cut a lot of weight (which I actually should not have done coz i lost muscle doing that) but nonetheless I dropped from 92 kgs to 81 while gaining some negligible muscle mass. I am cutting rn while gaining muscle, at 77.5 kgs.
I couldn't do a single push up or pull up 2 years ago. I was so unhealthy that I couldn't get up from the floor without using my hands. Now I can do 20-25 pushups in a row very easily.
Pullups are a different beast, I can do chin ups easily but pullups are tougher, still working on those.
Ok, so enough of my ramblings. Point being, diet is extremely important ngl. You can't get around this. Also, our normal pajeet diet is pretty shit for gaining muscle and losing fat. You need to eat salads, lean meat (if you eat non-veg) and/or eggs. Eggs are your best friend, eggs are superfoods. Cheap, good source of protein, easy to cook and very tasty. Learn to love them, to cook them in different ways since you will be eating a lot of them.
Oh also, give up rice completely.
That's my two cents, wish you luck on your fitness journey.
