You were refused under Paragraph 4.2 of the rules which means they do not believe you are a genuine visitor.
The paragraph having to do with booking.com is their way of saying that you did not study the guidance and hence possibly do not understand the rules. And by extension, people who do not understand the rules are likely to violate them. The assistant who examined your application most likely would have flagged your application as lower quality and so the other things you provided were examined as reduced quality when it was placed before the ECO.
The guidance is really clear that hotel confirmations are NOT part of the decision-making process unless they explicitly ask for them; and they hardly ever ask for them because their are too many ways to game the internet and confirmations do not establish intent to abide the rules. Also, they do not have the resources to verify those kind of things.
To fix that, you need to study the guidance and align your evidence accordingly.
The second reason is more interesting. Based upon everything you wrote, you apparently regularised in a country outside of your own country and under the legal aegis of your father. "Regularised" means you went from a temporary status (including an illegal status) to a more permanent status like a residence permit. So they conceded that you are legal in Saudi Arabia (that's a good thing).
The part about 'sponsorship of your father' means your status in Saudi Arabia is tied to his status and hence you have no status there as an independent person. If you add in the fact that you are living outside your own country, they can conclude that you have no ties to your home country and no tenable ties to Saudi Arabia. What this means is that you have no ties anywhere. That condition, by itself, is a show-stopper.
That type of situation requires extra diligence along with a high quality application. Knowing all of this makes it easy to understand your refusal. On the plus side, they did not make any imputations affecting your credibility; also they did not challenge your financial capacity.
To fix that part, you should probably regularise in Saudi Arabia as an independent person and make this really clear to them. This may help to establish ties. The other evidence needs to be high quality. You also need to make it clear that your evidence is informed by their guidance.
The part about 'no appeal' is telling you that you need to start from square 1 with a fresh application (including new biometrics). Understand that we are not the Tribunal and whatever defence or explanations you have will not change this answer or help you make a better application.
The rules are at Appendix V.

Applying for a visa for GMC ID Check is frequently rejected unless you satisfy UKVI officer regarding the purpose of your GMC Registration (and that is not easy). Since getting a job offer (for a doctor) in the UK does not need GMC registration, I would advise you to start applying for jobs and to do the ID check once you reach UK with a work-permit (TIER2) visa, and since you are only left with the ID check to finish GMC registration.
You can also omit mentioning the GMC ID check part and omit mentioning your employer and your job (since your sponsor in your residence permit is your father) and apply for a tourism visa bringing a bank statement from your father's account and a support letter from him to clarify that he is willing to support you for your trip.
