Yes, It's true , And Just how much deflection (slack)are we talking about?

Yes, If the block has been line bored. The machinist usually takes .002 or more from the block. The minimum amount will not bother the timing set too much. But as the amount removed gets larger. The chain gets loose. The only way tho correct is with correct timing set. I keep .005 and .010 sets in stock..

The sales people at auto stores probably don't know about line bore sets. They are usuallt only listed in high manufacturers performance/rebuilder catalogs.
