Can it be possible for me to start boxing and win championships (not small but world level competitions)?
You can, but you are not going to be a world champion.
You need to pick up your pace a bit in running. 40 mins 8000m at least.
Weights won't help you and will harm your speed and flexibility , you need skill, get down a boxing club.
