Since I believe it will be better if I first understand bitcoin's technical side before I proceed on the forum, I am currently beginning my journey with it from a technical standpoint.
But as I was researching, I found out that I first needed to download a file called the bitcoin core in order to start storing my bitcoin. In light of this, I want to know if there is any other way to store bitcoin besides downloading the core. And which is safer.

And if there is, I'd love it if the senior members could assist me with it. It seems to me that utilising the bitcoin core on a mobile device won't be much easier for me, so please let me know if you know of any way to store my bitcoin without downloading the complete bitcoin core.

Bitcoin Core is indeed a wallet, but is much more than that.
Bitcoin is a blockchain (list of blocks). Every single transaction that has ever happened is stored in this blockchain.
Let's say that I want to send you X amount of BTC. Bitcoin is digital, so I could fake it, right? Wrong! Every computer that runs Bitcoin Core, can download a FULL copy of the blockchain and have their own opinion to whether I have X amount of BTC to send. In order for this to happen, there needs to be a concesus (from the computers running Bitcoin Core) in regards to whether I really have this amount and I am not just faking it.
In fact without Bitcoin Core, there can be no Bitcoin. Even if you don't run Bitcoin Core (which is totally possible), you will need to connect to someone else's computer. So you need to trust THEIR opinions and at the same time, you lose privacy.
Bitcoin Core, also provides you with a wallet, as I said.

So, if you don't want to download Bitcoin Core and since you mentioned mobile device, you can download BlueWallet or Blockstream Green or any other wallet that other users suggest. These wallets will provide you with 12 or 24 words that you need to keep safe (offline) and away from anyone else. It is your wallet's backup. Losing it results to losing all your coins. If someone steals it, they can steal all your coins. Those wallet will connect to someone else's computer that runs bitcoin core.

A good tutorial for BlueWallet is here: https://www.youtube.com/watch?v=imMX7i4qpmg&ab_channel=BTCSessions. I suggest that you stop watching where he starts talking about Lightning because, for the time being, it will only confuse you. We will be here to discuss Lightning in the future.

I know you just started and it may sound difficult, but you can of course re-think my post after a while.
