Warnock makes history with Senate win as Dems near majority (AP News)

My takes below:

What does this mean?

This gives Democrats a thin majority in the senate. Does it mean they have free reign? No, the party is not that unified. In particular, as you probably have heard his name many many times now, Manchin, the "conservative Democrat" from WV is likely to be the kingmaker in votes. So it's not like just anything can get passed, and Manchin will not eliminate the filibuster easily.

So is it pointless?

ABSOLUTELY NOT

It's a huge victory nonetheless for Democrats. Remember, with control of the Senate, Chuck Schumer will be Senate Majority Leader, who controls what legislation the senate votes on. Even bipartisan bills were consistently torpedoed by McConnell who would refuse to even have a vote on it. Now, there is politics that can be done - deals, compromise, whatever. If you can't vote on something, nothing can be done. Things that are overall popular like increased stimulus are also going to pass.

Additionally, perhaps an even bigger deal, Biden can get his nominations through for cabinet and judges. There's an insane amount of unfilled heads of state departments right now, and the rest are filled with people absolutely unfit for the job. Having a real human being be the head of the EPA, or Department of Education, or the Department of Energy, and so forth is a big deal.

It also means that Justice Breyer can safely retire and have another "liberal" Justice take his place.

It's not sweeping control over the government, but it's a immensely superior political situation to McConnell stone walling anything he doesn't want, and Biden having to haggle with McConnell over how incompetent his cabinet needs to be.

It's really interesting and pretty useful to know how the 2 US parties are split and which voting blocks have dissappeared and emerged over time and some blocks don't really fit all too well in the 2 parties (most notably the religious left). This also serves as a kind of model for what a multiparty US might look like.
