Do order blocks show where institutions placed orders?

Not by themselves. A candle records prices over a period, not who traded or whether any orders remain. Evidence of large participation at a price comes from volume, absorption and resting size, and even then the identity and intentions of the participants are unknown.

How is an order block different from a supply or demand zone?

The definitions overlap. An order block is tied to a specific candle before a structure break; supply and demand zones are usually drawn around the base of a strong move. Both are hypotheses about where orders were concentrated, and both can be checked the same way with volume and order book data.

Order block

In 'smart money concepts' teaching, an order block is the last candle of the opposite color before a strong move that breaks market structure, taken to mark where large participants placed orders that may still be waiting. Candles cannot show orders; order flow tools can check whether that candle had heavy volume, absorption or resting liquidity, or none of these.

Definition as usually taught

A bullish order block is the last down candle before an impulsive up move that breaks a prior swing high; a bearish one is the last up candle before an impulsive down move that breaks a prior swing low. The candle's range, or its body, is then treated as a zone where price may react on a return, on the idea that institutional orders were filled there and more may remain.

What can be checked

Volume: did the candle trade heavily compared with its neighbors, or was it an ordinary bar?
Absorption: did aggressive selling in that candle meet bids that held, for a bullish block, as the footprint would show?
Resting liquidity now: when price returns, is there visible size on the heatmap or DOM in that zone, or is the book thin there?
Profile: is the zone a high volume node, where the market accepted price, or a thin area it passed through?

A worked example

A down candle trades from 4,998.00 to 4,995.00, then three up candles carry price to a close above the prior swing high at 5,005.00. The down candle is the bullish order block, 4,995.00 to 4,998.00. Case one: its footprint shows 1,800 contracts, its point of control at 4,996.00 and large bid volume at the low with price holding, absorption. Case two: it traded 300 contracts with nothing notable. The pattern is identical on candles; only in case one does the order flow support the idea that significant buying happened there.

In Senzoukria

The Break of Structure marker places a signal when a bar closes beyond the last confirmed swing, using strict pivots confirmed three bars each side by default, and its definition explicitly treats a wick that pierces and returns as a liquidity take rather than a break. The Absorption Zones overlay draws a rectangle over stacked absorbed levels and extends it until price returns, which is the order flow counterpart of a zone of interest. The heatmap shows whether resting size is present when price comes back, and the Volume Profile overlay shows whether the zone is a high volume node. There is no order block detector.
