No.  There might have been markers once, but perhaps they've not been 
maintained, or were fairly sparse in the first place.  The world is a 
big place, and the how routes are signposted varies hugely.  Something 
like https://www.openstreetmap.org/relation/400098 in sparsely populated 
Western Australia has far fewer signs than for example 
https://www.openstreetmap.org/relation/4080347 in England.

Knowing where the next signpost is certainly helps me (just as someone 
walking along the route) to figure out where the next bit goes, and to 
navigate around blockages.

I wouldn't underestimate the ability of OSM contributors to do that :)

Just to take a couple of examples near me, 
https://www.openstreetmap.org/relation/1996318 is pretty complete.  That 
one's sparsely signposted - it's across open moorland, so signposts 
don't really make sense for a lot of it.

https://www.openstreetmap.org/relation/370667 is also complete, and 
there signpost relation membership is definitely useful because some are 
missing, some refer to old versions of the route and some are just in 
the wrong place (an old public footpath fingerpost has been reused in 
error).

Best Regards,

Andy
