You can do the maths for this yourself to find out :)
Big utility battery installations are around $400/KWh IIRC and can cope with at least 2000 cycles[1]. Looking at the table you provided it looks like you'd be able to do around €50-€100 EUR per MWh sale per week on average if you're good at buying low and selling high but lack a crystal ball. So €0.05 per KWh and 2000 cycles still puts you in the red on your battery installation. :(
This is why most BESS's in Europe (and elsewhere) do revenue stacking to be profitable. This means they're not just doing arbitrage of intraday prices, but also providing ancillary services to the grid (so if there's e.g. a fault that causes the grid frequency to drop, a BESS will kick in and start to discharge at a power rate that stabilizes the grid frequency).
There's actually even more volatility than what is revealed in the dayahead table. Check intraday prices. They predictably go down at night and up at day (because while production is unpredictable, consumption is not).
