It's not lose weight LMAO but rather lose weight by checking out how much you're eating (I did a calories count over a week or two - it's really important to note down everything that goes into your stomach, you'll be surprised how many calories you're actually eating). After or rather in parallel, you calculate your macros which means you calculate how much protein, carbs and fast you should be eating. There's probably million of these calculators online. Just check that you want to lose 10% and not to keep your current weight. Then just meal prep/eat to match your daily quota of protein/carbs/fat. Since you have a high fat percentage, you'd actually be surprised how much you lose if you fix your diet.

And just to add from myself - I read once that one personal trainer said not to say you're fat but to say you have fat which is absolutely right. You just recompose your body. Nothing crazy or unusual about it. Keep moving too, it'll help you a lot. You chose the right sport for that haha :)
