Help with hackers

so not to long a ago I was pvping and a player named gotcha. Was attacking me and with my pro 4 I lose like half heart. But I was losing 2 hears per hit. He didn’t have strenth potion cause 1 no swirls round him 2 didn’t see him drink anything. So I died with it but I’m kinda sad. But I’m wondering if he had hacks or bookshelf mod which gives u better enchantments

i know I don’t have pics of it but u can ask 1diggerboy1 he died bye him also. And anotuer thing gotcha didn’t have enchanted armor and I hit him a few times  so I don’t know if he was cheating.
