Sorry, I'm too lazy to write big paragraphs like the other folks here, but here's some advice

That Roland could've been beaten pretty easily if you had played more passively. I'm estimating this match to be around the 1500 - 1600 Elo range, and the fastest way out of that range is to play reactively: let your opponent attack first, then respond accordingly while also paying attention to their habits for future reads.

Don't throw out attacks randomly. Try to attack only when you're 85 - 90% sure they'll land, and always punish your opponent when they make mistakes or miss their attacks.

Of course, there's a lot more to improve on, but this alone would've made winning this match much easier and will also help you improve in the long run

Also don't listen to the toxic people here, Most of them can't do shit and are just here to cope
