Concerns Regarding Paris Olympics Ticket Resale?

Is anyone else worried that they might not be able to sell their tickets when the resale platform opens in mid May? I bought tickets to 7 different games, but after finalizing our itinerary we'll likely only be able to attend 2 of them. The other 5 that we plan to sell are less popular games like soccer, archery, water polo, etc.

I feel like there might be excess tickets to these games and thus people won't buy them on the resale platform and it'll end up as a sunk cost. What do others think?
