At some point, things will return to normal in terms of clubbing and the university social experience. I don't think a lack of clubbing opportunities is a big enough reason to delay going to university, unless you have a solid plan for your gap year. Remember, you will want to keep your skills up for the following year of university and it can be hard to motivate yourself to do things that are constructive and useful. I think, unless you have a job lined up already, you may struggle to find one - depending on where you live. Covid-19 has created an employment crisis.
Depending on your degree, online learning won't necessarily be too different from actually attending lectures. I finished university in 2017 and completed an English degree (which has minimal contact hours compared to a lot of other degrees). My university recorded lectures and uploaded resources, so - if I couldn't attend in person - I could just catch up online. I'm not saying this is ideal, but at points during my degree, my attendance plummeted a bit. Luckily, the recorded lectures were the same as being in the lecture hall - in fact, in many ways, recorded lectures were better as I could pause the talk, rewind it, and take more detailed notes (some of the lecturers spoke so quickly, I couldn't keep up). I think seminars can be held online (via platforms like Zoom) and will be just as effective as being in a room with other students and a lecturer (again, this is subject-dependent).
I think there is a problem with suggesting that, just because you aren't on campus, being taught in person, the education won't be the same. Certainly, the social experience might not be the same - at least, at the start it won't be - but with a vaccine in the pipeline, I don't think things will be as dire for long.
