Then you won't accomplish what you want. You need to read. You'll stop making embarrassing mistakes like using "segway" in a sentence once you start reading. "Educational videos" are for imbeciles who want to watch TV while pretending they're not just watching TV.
Where to go to learn history?

To be fair, it doesn't say Poland, only Poles, which might have been a general ethnic term for Slavs (i.e. non-Germanics, non-Baltics) east of the Oder.

Lechs are more prolific than you think. Czeruski took down the Romans.

Listen to Hardcore History. Dan Carlin is pretty even-handed in his explanations.

No offense to you or to the others, but not one of these recommendations mean dick if you can't read or write. You don't understand what I mean, so I've included an infographic to help. You'll understand more once you're halfway through pic-related.
You need a full reset.
If you're serious about this, you've got to stop coming here for anything but occasional amusement. Go to your local library and check out 2-3 books (starting with the ones in pic related).
Once you're through the first 3 books, you will more than likely already have an idea of what you're next steps should be.
Resources: your local library, Gutenberg books, torrent sites for free books. I'll see if I have a PDF of the first task for you.

The episodes have become free to watch. It covers 300AD to 1460AD in a lot of detail. The author is clearly pro-European and pro-Catholic, but generally comes at the history from a relatively neutral position. Extreme detail given to religion, politics and war; some stuff on the general culture and day-to-day life. Gives a very solid understanding of what happened and why it happened, and you can clearly see why X led to Y - which for me was a huge deal. I always knew a lot about history but it was difficult for me to get the chronology correct; I just knew a lot of details in a vacuum. This series explains how one thing led to the next thing which gives a huge amount of understanding.
You can also see how we got to where we are today which is fascinating. I 100% recommend it.

Where do I start with learning the Greeks and Romans? I have read intro books and would like to go deeper.

Not quite. The general term for West Slavs was Wends but various tribes of course had their own names. Around early 9th century the Polans, an influential tribe from Western Poland ultimately subjugated other smaller tribes and emerged as the dominant power in the region under the leadership of the Piast dynasty. Piasts most likely pulled off a Carolingian style coup d'etat and overthrown the previous, unknown to us by name dynasty and usurped their place. The name Poland is derived from the Polan tribe.
