No. https://www.nilight.com/products/nilight-272pcs-standard-min... These are not slow burning fuses or whatever. In their product video 6A blows a 5A fuse in like subseconds. However 6/5 rated current should probably blow slower, like days, or not at all? The 2A fuse is probably just made faulty. Edit:
Of course, the Amazon seller could be a counterfeit of "Nilight", which might be a proper brand? |

Those brands can be found on sites engineers shop on, like Digikey, Mouser, Newark, and similar (which also lets you price / order by the thousands, and feed into manufacturing channels, rather than by boxes of random parts). They will have datasheets, rather than Youtube videos. Better datasheets will often show:
* Typical and worst-case behavior
* I²t, which is used to compute how long it will conduct a given current
* Impact on ambient temperature on rated current
... and similar
Here's a few random fuse data sheets from Mouser:

Some of these are more complete, and some less. That's a fact of life. I can buy a fancy fuse which specs and tests everything for a bit more $$$ for a medical or military application, or one which doesn't for $ for e.g. a toy. If all I'm worried about is a short, that's good enough.
A Youtube video which shows a 5A fuse blowing at 6A means either:
1. The video was baked for Youtube.
2. The fuse will blow at 4A on a hot summer day, running in an even hotter enclosure, and you've bought a bad fuse.
My bet is on #1.
