I have had trouble understanding these notions, but your video explained it very well thanks a lot. Also thank you for caring for my eyes and choosing a dark background with colours.

Nicely explained but you haven't include snapshot isolation in above.

05:57 in this part, when he says "now if this query is run again", does he say "query" referring to the transaction? "now if this transaction is run again"? Or is he referring to the read query inside the transaction?

when two people add amount to a bank at the same time then
how REPEATABLE READ will help

for example, B and C are transferring 100 to A with a bank balance 200
then for After B transfer balance will be 300
After the C transfer balance will be 300

then balance remains 300 but it should be 400

@ 6:30 based what you said, it appears that the phantom phenomena is similar to non-repeatable read. I am unable to differentiate the 2. Both are experiencing different values between reads.
