ELI5: How can information be transmitted so accurately with little to no errors even at several MB/s?

If I'm not wrong, information is transmitted in 0s and 1s which is binary.   
0s replaced by 1s or vice versa is all it takes to corrupt a file. How is this not prevalent even at high speeds? Even slight disturbance or delay could destroy such fragile signals.

The most common protocol used for communication is TCP/IP which includes mechanisms to confirm all the data is received accurately.

Data transferred over the internet is broken into smaller chunks called packets. That way if a file gets damaged during transport only a small part of it (a single packet) will be affected.

Packets are typically 1500 bytes, or 1.5kb in size

In addition to source + destination, filename, etc Each packet includes a verification called a checksum.

Think of the checksum like a skill testing question

4 x 7 = 28

When the packet is received the checksum is verified. If it has become damaged then the checksum will no longer be valid and the receiver  sends a message to re-transmit that packet.

3 x 7 = 28 ERROR

Once all the packets for a file have been received and verified, the file is re-assembled.

Not all traffic is verified in this way though. Instead of TCP some types of traffic use UDP which is 'best effort' protocol. This is used for things like voice chat and video that operate in real time and can afford to have a couple of errors during the transfer process.
