You don't need equipment to start calisthenics. You can do almost every exercise without any equipment. For pull-ups, you can buy a doorway pull-up bar; it's cheap but if you can't, just find a place to hang and you can do pull-ups. For dips, if you can't buy a dip bar, just take two chairs and place them parallel, and you can do dips. That's it. You don't need anything; just focus on consistency.

@Fair War If you can't do an exercise, you can do an easier progression, like if you can't do pushups, you can do knee pushups or inclined pushups, and then slowly you will build the strength to do the actual exercise. If you are a teenager, you should not cut and just main gain. If you want less fat around your jawline, I think it will happen when you cut. I know you want to look good and have an aesthetic physique because you are a teenager and as teenagers, we want attention and people to praise us for looking cool. But don't run after an aesthetic physique or a low body fat percentage. If you want to look good just workout, work hard, and eat healthy. Make sure you eat enough protein (1.8 - 2.2g per kg of body weight). Just be consistent and trust the process!
