No.
Is my Bitcoin in my account?
No.
Do I hold my Bitcoin?
No.
So where the hell is my Bitcoin and what is it that I own?
Bitcoin is permanently residing on the Bitcoin Blockchain and you are holding private keys that unlock your Bitcoin whenever you need to interact with it.
It is like owning private keys to a very lucrative digital property.

So how do I secure my keys then?

This my friend is your main task and should be a field of your study.

It can be your memory if your trust it.
It could be a piece of paper or a steel plate.
It could be a special hardware wallet that stores it for you or a version of cold wallet that holds the keys as long as it is powered and erases them when it's off / nostr:npub17tyke9lkgxd98ruyeul6wt3pj3s9uxzgp9hxu5tsenjmweue6sqq4y3mgl /

Focus and good luck. 👍🏼
